Abstract
After a review of the canonical reduction to the rest-frame Wigner-covariant instant form of standard theories in Minkowski spacetime, a new formulation of tetrad gravity is introduced. Its canonical reduction, in the presence of N scalar particles, is carried out. A modification of the ADM formulation to solve the deparametrization problem of general relativity (how to recover the rest-frame instant form for G = 0) is presented.
