1 Basic Idea, Can Two First Integrals Give Equivalent Information? This Is Due to the First Reference

We use a construction for a mass of a graviton from Beckwith (2018). Instead of Hamber’s (Beckwith 2018; Hamber 2009) first integral, we use what John Klauder wrote in Klauder (2015) to form a first integral in Beckwith (2018) so as to make a 1 to 1 equivalence with the first integral of general relativity (Dalarsson and Dalarsson 2005; Weinberg 1972). As in Beckwith (2018) we have a 1 to 1 relationship between two first action integrals. We avoid starting with a cosmic singularity, and use the cosmic bounce, as given in Rovelli and Vidotto (2015). In doing so, from Beckwith (2017, 2018) we use a barrier between interior and exterior space-time, to set up a cosmological constant. Our goal is to set up arguments which have no connection to the anthropic principle (Barrow and Tipler 1988) which the author regards as crackpot science of the worst sort. Having a clean break from the anthropic principle is a main goal of our enterprise.

1.1 This Is Our Argument for the GR First Integral: From Beckwith (2018)

The first integral used in Beckwith (2018) is also in a first integral (Padmanabhan 2005) of the form given by Eq. (3.1), having a Ricci scalar (Padmanabhan 2006). Also, the curvature is small. Therefore

$$ {\displaystyle \begin{array}{c}{S}_1=\frac{1}{2\kappa}\int \sqrt{-g}\cdot {\mathrm{d}}^4x\cdot \left(\Re -2\Lambda \right)\\ {}\&-g=-\det {g}_{uv}\\ {}\&\Re =6\cdot \left(\frac{\ddot{a}}{a}+{\left(\frac{\dot{a}}{a}\right)}^2+\frac{\aleph }{a^2}\right)\end{array}} $$
(3.1)

Also, \( \delta {g}_{tt}\approx {a}_{\mathrm{min}}^2\phi \) (Beckwith 2016; Giovannini 2008) uses inflaton, ϕ (Padmanabhan 2006). Which if we abide by Beckwith (2018) and Padmanabhan (2006)) we have

$$ a(t)={a}_{\mathrm{min}}\cdot {t}^{\gamma } $$
(3.2)

Padmanabhan, in (2006), states Eq. (3.2) above leads to the Beckwith (2018) and Padmanabhan (2006)) inflaton.

$$ \phi \approx \sqrt{\frac{\gamma }{4\pi G}}\cdot \ln \left\{\sqrt{\frac{8\pi {GV}_0}{\gamma \cdot \left(3\gamma -1\right)}}\cdot t\right\} $$
(3.3)

Here amin is a minimum value of the scale factor (Beckwith 2018; Camara et al. 2004) which may have an electromagnetic contribution as given in Camara et al. (2004).

2 Next from Klauder Details Which Are Used to Give More Q.M. Structure

Note (Beckwith 2018) we are using a restricted quantum action principle (Klauder 2015) S2, Eq. (3.4), when we assume for simplicity that Λ is a constant.

$$ {\displaystyle \begin{array}{c}{S}_2={\int}_0^T\mathrm{d}t\cdot \left[p(t)\dot{q}(t)-{H}_N\left(p(t),q(t)\right)\right]\\ {}\approx {S}_1=\frac{1}{2\kappa}\int \sqrt{-g}\cdot {\mathrm{d}}^4x\cdot \left(\Re -2\Lambda \right)\end{array}} $$
(3.4)

Hence

$$ \Lambda \approx \frac{-\left[p\left(\tilde{t}\right)\dot{q}\left(\tilde{t}\right)-{H}_N\left(p\left(\tilde{t}\right),q\left(\tilde{t}\right)\right)\right]}{\frac{1}{\kappa}\int \sqrt{-g}\cdot {\mathrm{d}}^3x}+\frac{\frac{1}{2\kappa}\int \sqrt{-g}\cdot {\mathrm{d}}^3x\cdot {\left.\left(\Re =6\cdot \left(\frac{\ddot{a}}{a}+{\left(\frac{\dot{a}}{a}\right)}^2+\frac{\aleph }{a^2}\right)\right)\right|}_{t=\tilde{t}}}{\frac{1}{2\kappa}\int \sqrt{-g}\cdot {\mathrm{d}}^3x} $$
(3.5)

3 Filling in the Details of the Above Using Details from Klauder (2015) with Explanations

First

  1. (a)

    That S2 ≈ S1 from pre-Planckian to Planckian space-time when we avoid the cosmic singularity (Beckwith 2018). We ask that our model be consistent with the cosmology associated with a cosmic bounce, instead of a traditional singularity (Beckwith 2017)

  2. (b)

    Also curvature will be a small part of Ricci scalar (Novello n.d.)

$$ \Re =6\cdot \left(\frac{\ddot{a}}{a}+{\left(\frac{\dot{a}}{a}\right)}^2+\frac{\aleph }{a^2}\right)\sim 6\cdot \left(\frac{\ddot{a}}{a}+{\left(\frac{\dot{a}}{a}\right)}^2\right) $$
(3.6)

Furthermore, assume that there is a barrier between the pre-Planckian and Planckian physics regimes, so that we have a quantum mechanical potential well, using Beckwith (2017) which has Klauder’s (2015) notation that N represents the strength of the wall.

$$ {\displaystyle \begin{array}{c}\frac{p_0^2}{2}=\frac{p_0^2(N)}{2}+N;\kern1em \mathrm{for}\;0<N\le \infty \\ {}q={q}_0\pm {p}_0t\\ {}{V}_N(x)=0;\kern1em \mathrm{for}\;0<x<1\\ {}{V}_N(x)=N;\kern1em \mathrm{otherwise}\\ {}{H}_N\left(p(t),q(t)\right)=\frac{p_0^2}{2}+\frac{{\left(\mathrm{\hslash}-\pi \right)}^2}{2}+N;\kern1em \mathrm{for}\;0<N\le \infty \end{array}} $$
(3.7)

We set q = q0 ± p0t~ϕ and assume small time steps, and the scale factor is given by Camara et al. (2004)

4 Why This Is Linked to Gravity/Massive Gravitons

Klauder’s program is to isolate a regime of space-time for a canonical quantization of a classical system. That is, what we did is to utilize the ideas of Klauder (2015) to make the identification of Eq. (3.7) which when combined with enhanced quantization of the, as given in Eq. (3.3). That is, assume\( \sqrt{-g} \) is a constant. And this is for extremely small-time intervals (in the boundary between pre-Planckian to Planckian physical boundary regime). As given by Giovannini (2008) in his comprehensive review of cosmological production of gravitons and early universe entropy. This approximation is why \( {g}_{tt}\sim \delta {g}_{tt}\approx {a}_{\mathrm{min}}^2\phi \).

If so, the mass of a graviton is referred to, as given by Novello (n.d.). We can then write a bound, based upon the early universe conditions so set forth, as a way to ascertain a bound to the effective heavy graviton (Beckwith 2014, 2018; Novello n.d.)

$$ {m}_{\mathrm{g}}^2={\left(\frac{\mathrm{\hslash}\cdot \sqrt{\Lambda}}{c}\right)}^2\approx \frac{{\mathrm{\hslash}}^2}{c^2}{\left[\frac{-\left[\frac{V_0}{3\gamma -1}+2N+\frac{\gamma \cdot \left(3\gamma -1\right)}{8\pi G\cdot {\tilde{t}}^2}\right]}{\frac{1}{\kappa}\int \sqrt{-g}\cdot {\mathrm{d}}^3x}+{\left.\left(6\cdot \left(\frac{\ddot{a}}{a}+{\left(\frac{\dot{a}}{a}\right)}^2\right)\right)\right|}_{t=\tilde{t}}\right]}_{\tilde{t}=t\left(\mathrm{Planck}\right)} $$
(3.8)

Our next step is to review the input of parameters which may affect Eq. (3.10). To do so we consider a multi universe generalization of the CCC as given below. This is done specifically to kill off references to the anthropic principle as far as Eq. (3.8) (Barrow and Tipler 1988).

5 Reviewing Multiverse Generalization of the CCC of Penrose, and How This Relates to Beckwith’s (2018) Conclusions

We are extending Penrose’s suggestion of cyclic universes, black hole evaporation, and the embedding structure our universe is contained within. The following is largely taken from Beckwith (2014, 2018) and Penrose (2011) and has relevance to the final part of the conclusion. That there are no fewer than N(Penrose style ccc) universes undergoing Penrose “infinite expansion” (Penrose) (Beckwith 2014, 2018; Penrose 2011) contained in a mega universe structure. Furthermore, each of the N(Penrose style ccc) universes has black hole evaporation, with the Hawking radiation from decaying black holes. If each of the N(Penrose style ccc) universes is defined by a partition function, called \( {\left\{{\Xi}_i\right\}}_{i\equiv N}^{i\equiv 1} \), then there exist an information ensemble of mixed minimum information correlated as about 107 − 108 bits of information per partition function in the set \( {\left.{\left\{{\Xi}_i\right\}}_{i\equiv N}^{i\equiv 1}\right|}_{\mathrm{before}} \), so minimum information is conserved between a set of partition functions per universe

$$ {\left.{\left\{{\Xi}_i\right\}}_{i\equiv N}^{i\equiv 1}\right|}_{\mathrm{before}}\equiv {\left.{\left\{{\Xi}_i\right\}}_{i\equiv N}^{i\equiv 1}\right|}_{\mathrm{after}} $$
(3.9)

However, there is non-uniqueness of information put into each partition function \( {\left\{{\Xi}_i\right\}}_{i\equiv N}^{i\equiv 1} \). Furthermore, Hawking radiation from the black holes is collated via a strange attractor collection in the mega universe structure to form a new big bang for each of the N (Penrose CCC style) universes represented by \( {\left\{{\Xi}_i\right\}}_{i\equiv N}^{i\equiv 1} \). The nf value will be using Ng (2008) Sentropy~nf (Beckwith 2014, 2018; Ng 2008). This assumes an energy expression as given by Beckwith (2014, 2018) and Poplawski (2011) and as by Beckwith (2018) will be an energy conservation equation before and right after the big bang, for the structure of our local universe, so formed in our modified CCC argument. Then the following holds (Beckwith 2014, 2018; Penrose 2011),

Claim 3.1

$$ \frac{1}{N}\cdot \sum \limits_{j=1}^N{\left.{\Xi}_j\right|}_{j\hbox{-} \mathrm{before}\hbox{-} \mathrm{nucleation}\hbox{-} \mathrm{regime}}\underset{\mathrm{vacuum}\hbox{-} \mathrm{nucleation}\hbox{-} \mathrm{tranfer}}{\to }{\left.{\Xi}_i\right|}_{i\hbox{-} \mathrm{fixed}\hbox{-} \mathrm{after}\hbox{-} \mathrm{nucleation}\hbox{-} \mathrm{regime}} $$
(3.10)

And

$$ {\left.{\Xi}_j\right|}_{j\hbox{-} \mathrm{before}\hbox{-} \mathrm{nucleation}\hbox{-} \mathrm{regime}}\approx \sum \limits_{k=1}^{\operatorname{Max}}{\left.{\tilde{\Xi}}_k\right|}_{\mathrm{black}\hbox{-} \mathrm{holes}\hbox{-} j\mathrm{th}\hbox{-} \mathrm{universe}} $$

For N (Penrose style ccc) number of universes, with each Ξj|j ‐ before ‐ nucleation ‐ regime for j = 1 to N(Penrose style ccc) (Beckwith 2014, 2018; Penrose 2011) being the partition function of each universe just before the blend into the RHS of Eq. (3.11) above for our present universe. Also, each of the independent universes given by Ξj|j ‐ before ‐ nucleation ‐ regime is constructed by the absorption of black holes taking in energy. I.e., (Penrose) (Beckwith 2014, 2018; Penrose 2011). Furthermore, Eq. (3.11) uses the idea of Dye (1965) in terms of general ergodic mixing.

This is after we make the following identification, i.e., look at the formation of a nontrivial gravitational measure as a new big bang for each of the N universes as by n(Ei)⋅ the density of states at a given energy Ei for a partition function (Beckwith 2014, 2018; Poplawski 2011).

Claim 3.2

$$ {\left\{{\Xi}_i\right\}}_{i\equiv 1}^{i\equiv N}\propto {\left\{{\int}_0^{\infty}\mathrm{d}{E}_i\cdot n\left({E}_i\right)\cdot {\mathrm{e}}^{-{E}_i}\right\}}_{i\equiv 1}^{i\equiv N} $$
(3.11)

What is done in Claim 3.1 and Claim 3.2 is to come up with a protocol as to how a multi-dimensional representation of black hole physics enables continual mixing of space-time (Hawkings n.d.) largely as a way to avoid the anthropic principle (Barrow and Tipler 1988), as to a preferred set of initial conditions.

Claim 3.1 which uses Claim 3.2 is important. The idea here is to use what is known as CCC cosmology (Beckwith 2014, 2018; Penrose 2011), which can be thought of as the following. First. Have a big bang (initial expansion) for the universe. After redshift z = 10, a billion years ago, SMBH formation starts. Matter-energy is vacuumed up by the SMBHs, which at a much later date than today (present era) gather up all the matter-energy of the universe and recycle it in a cyclic conformal translation. As given, by the transformations alluded to in Eqs. (3.12) and (3.13) below. So we can thereby understand the change in CCC space-time geometry.

Note that the main methodology in the Penrose proposal (Beckwith 2014, 2018; Penrose 2011) has been evaluating a change in the metric gab by a conformal mapping \( \hat{\Omega} \) to

$$ {\hat{g}}_{ab}={\hat{\Omega}}^2{g}_{ab} $$
(3.12)

Penrose’s suggestion has been to utilize the following (Beckwith 2014, 2018; Penrose 2011)

$$ \hat{\Omega}\underset{ccc}{\to }{\hat{\Omega}}^{-1} $$
(3.13)

In fall into cosmic black hopes has been the main mechanism which will be useful for the recycling apparent in Eq. (3.14) above with ℏ kept constant from cycle to cycle as represented by Beckwith (2014, 2018)

$$ {\mathrm{\hslash}}_{\mathrm{old}\hbox{-} \mathrm{cosmology}\hbox{-} \mathrm{cycle}}={\mathrm{\hslash}}_{\mathrm{present}\hbox{-} \mathrm{cosmology}\hbox{-} \mathrm{cycle}} $$
(3.14)

We claim that Eq. (3.14) with Eq. (3.8) and Eq. (3.10) above gives a uniform mass to a graviton, per cycle, if Equation (3.14) holds we have the ability to make gravitons keep a constant non zero mass from cycle to cycle of the CCC paradigm. The idea is to keep consistency in physical law during each cycle of CCC dynamics. If the laws of laws of physics remain invariant , then graviton mass will not be altered. This also involves the physics of Ng (2008), Poplawski (2011), and Hawkings (n.d.). In doing so, from Beckwith (2018) consider the dynamics of the scale factor a(t), which is nearly zero, in the pre-Planckian regime of space-time. i.e., as to how a(t) changes and evolves, we look at the treatment given in Roos (2003) as well as Dye (1965). In addition by Beckwith (2018) and Hamber (2009).

$$ {\displaystyle \begin{array}{c}\int \mathrm{d}t\sqrt{g_{tt}}{V}_3(t)={V}_4(t)\sim 8{\pi}^2{r}^4/3\\ {}\&{V}_3(t)=2{\pi}^2a{(t)}^3/3\\ {}\&{k}_2=9{\left(2{\pi}^2\right)}^{2/3}\end{array}} $$
(3.15)

These are volume elements of the Hamber (2009) first integral. i.e., see Ambjorn et al. (2010), Karabulut (2006), Spiegel (1980). A Lagrangian multiplier is a constraint of how a “minimal surface” is obtained by constraining a physical process so as to use Ambjorn et al. (2010), Karabulut (2006), and Spiegel (1980). In the case of Karabulut (2006), the minimization process is if a(t) a scale factor as defined by Dye (1965) and gtt a time component of a metric tensor. Here, the subscripts 3 and 4 in the volume refer to 3- and 4-dimensional spatial dimensions, and this will lead to, via Hamber (2009), a first integral as defined by Beckwith (2018) and Hamber (2009), in the form, if G is the gravitational constant,

$$ {S}_1=\frac{1}{24\pi G}\cdot \left(\int \mathrm{d}t\sqrt{g_{tt}}\left(\frac{g_{tt}{\dot{V}}_3^2}{V_3(t)}+{k}_2{V}_3^{1/3}(t)-\lambda {V}_3(t)\right)\right) $$
(3.16)

This should be compared against the Padmanabhan first integral (Barrow and Tipler 1988; Padmanabhan 2005), with the third entry of Eq. (3.3) having a Ricci scalar defined via Weinberg (1972) and usually the curvature (Weinberg 1972) set as extremely small, with the general relativity version of from Beckwith (2018) of Eq. (3.1). Note that our write-up actually uses all this and aligns it with the ideas of the Klauder enhanced quantization (Klauder 2015) for what we think is a better extension of the same idea. In order to obtain maximum results, we will be stating that the following will be assumed to be equivalent, i.e., in the spirit of Beckwith (2018)

$$ \sqrt{g_{tt}}\left(\lambda {V}_3(t)\right)\sim \frac{1}{2\kappa}\int \sqrt{-g}\cdot {\mathrm{d}}^3x\cdot \left(2\Lambda \right) $$
(3.17)

So, from Beckwith (2018), a relationship of the Lagrangian multiplier:

$$ \lambda \sim \frac{1}{\kappa}\sqrt{\frac{-g}{\left(\delta {g}_{tt}\approx {a}_{\mathrm{min}}^2\phi \right)}}\cdot \Lambda $$
(3.18)

We are obtaining the exact same physics, as in Beckwith (2018) for when we appeal to Eq. (3.8) as a bound to the enhanced quantization, hence we have extended our basic idea via use of Beckwith (2018) and Klauder (2015). To conclude with this mini section, this is included in as a way to set up a statistical averaging procedure as to avoid the anthropic principle. After having said this, if our Eq. (3.11) has successfully set up a program to avoid the anthropic principle (Barrow and Tipler 1988), we can relate this to massive gravitons, next and early universe entropy.

6 Why This Is Linked to Gravity/Massive Gravitons, and Possibly Early Universe Entropy

Klauder’s program (Klauder 2015) is to embed via Eq. (3.8) as a quantum mechanical well for a pre-Planckian system for inflaton physics as given in Beckwith (2018) where we go to the idea as given in Klauder’s treatment of the action integral as of page 87 of Klauder (2015) where Klauder talks of the weak correspondence principle, where an enhanced classical Hamiltonian is given 1–1 correspondence with quantum effects, in a non-vanishing fashion. If so, by Novello (Camara et al. 2004) and Eq. (3.8) we have then for early universe conditions, that we will be leading up to using an algorithm for massive gravitons, as we were working with in Beckwith (2018) with the result that we write, for a Plank time value is to go back to our Eq. (3.8) which we subsequently turn into Eq. (3.11) where we use the convention for scale factors as given in Camara et.al. (Giovannini 2008) so that we have a tentative value of the cosmological constant and then by extension the graviton mass via Novello (Camara et al. 2004) of Eq. (3.11). The long and short of it is to tie this value of the cosmological constant, and the production of gravitons due to early universe conditions, to a relationship between De Broglie wavelength, Planck length, and if the velocity v gets to a partial value close to the speed of light, that, we have, say by using Landau and Lifshitz (2005) as given in DICE 2018 and also part of the JHEPGC publication for quantum systems, if we have instead of a velocity much smaller than the speed of light, a situation where the particle moves very quickly (a fraction of the speed of light) that instead of the slow massive particle postulated in Landau and Lifshitz (2005)

$$ {\displaystyle \begin{array}{l}{\lambda}_{\mathrm{De}\hbox{-} \mathrm{Broglie}}\approx \frac{2\pi \mathrm{\hslash}}{m_gv}\cdot \sqrt{1-\frac{v^2}{c^2}}\cong {\mathrm{\ell}}_{\mathrm{Planck}}\approx \sqrt{\frac{\mathrm{\hslash}G}{c^3}}\\ {}\Rightarrow \mathrm{if}\;v\left(\mathrm{particle}\right)\to c-{\xi}^{+};\mathrm{then}\\ {}\varepsilon \left(\mathrm{energy}\hbox{-} \mathrm{particle}\right)\approx {E}_{\mathrm{Planck}}\left(\mathrm{Planck}\hbox{-} \mathrm{energy}\right)\end{array}} $$
(3.19)

Let us start with a specified value of mass of a graviton, say of the order of 10–62 g and also the application of the Ng “infinite quantum statistic” counting algorithm with S (entropy) being equivalent to the number of generated gravitons, which we call n. We will then use the construction of cyclic conformal cosmology (ccc) given by Penrose (2011) so that

$$ {\displaystyle \begin{array}{l}\mathrm{If}\;c\equiv 1,{m}_{\mathrm{g}}\approx {10}^{-62}\;\mathrm{g}\\ {}{E}_{\mathrm{Planck}}\left(\mathrm{Planck}\hbox{-} \mathrm{energy}\right)\cong 2.18\times {10}^{-5}\;\mathrm{g}\\ {}\cong \left({m}_{\mathrm{g}}\approx {10}^{-62}\;\mathrm{g}\right)\times N\left(\mathrm{entropy}\hbox{-} \mathrm{number}\right)\\ {}\Rightarrow N\left(\mathrm{entropy}\hbox{-} \mathrm{number}\right)\cong {10}^{58}\equiv {10}^{\mathrm{\mathbb{N}}},\mathrm{and}\therefore \mathrm{\mathbb{N}}\cong 58\end{array}} $$
(3.20)

7 Can This Tie in with Early Universe e Folds? That Is, from Chongchitnan (n.d.) e Folds Are Between 55 and 60

E folds in cosmology are a way of delineating if we have enough expansion of the universe in line with inflation. As seen in Chongchitnan (n.d.), we can have

$$ \mathrm{\mathbb{N}}\left(\mathrm{e}\hbox{-} \mathrm{fold},\cos \mathrm{mol}\right)\approx -\int \mathrm{d}t\cdot H\left(\cos \mathrm{mol}\right) $$
(3.21)

where H(cosmol) is a value of the Friedman equation, and if we use the idea that the potential energy, V, of initial inflation is initially over shadowed by the contributions of the Friedman equation, H, at the onset of inflation. Then

$$ \mathrm{\mathbb{N}}\left(\mathrm{e}\hbox{-} \mathrm{fold},\mathrm{cosmol}\right)\approx 55-60 $$
(3.22)

What we wish to explore is if Eq. (3.22) is consistent with Eq. (3.23) and what the consequences will be of this identification

$$ N\left(\mathrm{entropy}\hbox{-} \mathrm{number}\right)\cong {10}^{58}\equiv {10}^{\mathrm{\mathbb{N}}},\mathrm{and}\therefore \mathrm{\mathbb{N}}\cong 58 $$
(3.23)

Doing so may involve use of the Corda article, as given in Corda (2018).

8 Conclusion, Does Our Bound as to the Graviton Mass, and Its Input Variables Due to Klauder Enhanced Quantization Argue in Favor of a Quantum Gravity Linkage to e Folds and Inflation? This Needs to Be Determined Next

We argue that we may have inputs into the building of a bound to the mass of a graviton if a multiverse may contribute to the construction of the graviton mass. That is the input side of the phenomena used for getting a bound to the massive graviton, and the use of the Novello (Camara et al. 2004) supposition of a linkage between massive gravity and an allowed cosmological constant. An output version of this phenomena after we create a necessary condition for massive gravity is in the issue raised by Eq. (3.8). And also the intriguing possibility of more overlap between Eqs. (3.22) and (3.23). If there is an overlap of these two Eqs. (3.22) and (3.23), which raises the intriguing question of if a mass of a graviton, i.e., a quantum gravity lodestone is in fidelity with the e folds of cosmology, then we have the distinct possibility of quantum gravity having at least a partial linkage to e fold inflationary cosmology. If this is not true, then tensor-scalar version of gravity and other models need a very hard look over. And while we are on the subject, Appendix A, as given below is yet another datum which needs experimental vetting. All these together would be needed to be confirmed via experimental gravitational data sets. A side note which is to consider is, if this happens, does it in any way have linkage to the idea of forming symmetries in space-time which could lead to SU(n) type group thinking? See Dyson (1966) as the gold standard. We can only go there though if we understand the physical input phenomena as to the creation of a burst of inflationary energies later, and if we have quantifiable data sets to come up with readily understood models. With falsifiable input parameters. This is our hope and our aspiration as of the twenty-first century as far as gravitational experimental science.

Finally what if there are many micro black holes created almost at the start of the Universe? What would this do in terms of GW generation? See Appendix B, as a future works project which may add more context as far as the varying mechanisms as far as GW, and our project is so delineated. This is in terms of entropy, itself and is a much smaller contribution of entropy than what is already delineated. But if we develop GW physics as an experimental science, this too may be something not to ignore and will involve the physics of Chongchitnan (n.d.), Corda (2018), and Dyson (1966) fully.
