We consider three examples of alternative theories of gravitation which depend on quadratic invariants of the Ricci tensor. By means of a canonical gauge fixing, we prove that such theories are dynamically equivalent to standard Einstein’s theory with gravitational constant and external matter fields.

Abstract
We consider three examples of alternative theories of gravitation which depend on quadratic invariants of the Ricci tensor. By means of a canonical gauge fixing, we prove that such theories are dynamically equivalent to standard Einstein’s theory with gravitational constant and external matter fields.File in questo prodotto:
