Variational formulation of two scalar-tetradic theories of gravitation

D. Sáez

Open publisher page 49 citations

Abstract

In this paper we obtain two scalar-tetradic theories of gravitation (theories A and B) from a variational principle. In these theories the gravitational energy is localized and the principle of equivalence holds. They combine some aspects of M\o{}ller theory and the Brans-Dicke theory. The first-order approximations and an introduction to the study of both theories in the static spherically symmetric case are presented.
