Abstract
Cosmology with the gravitational and cosmological constants generalized as coupling scalars in Einstein's theory is considered. A general method of solving the field equations is given. Fifteen exact solutions for zero pressure models satisfyingG=G 0(R/R 0)nare given in the Appendix; they are briefly discussed.
