Description

1. Introduction Several new theories of gravitation have been formulated which are considered to be alternative to Einstein's theory of gravitation. In alternative theories of gravitation, scalar tensor theories proposed by Brans and Dicke [1], Nordvedt [2], Wagoner [3], Ross [4], Dunn [5] and Saez and Ballester [6] are most important among them. In the theory proposed by Brans and Dicke [1] there exists a variable gravitational parameter G. Another theory, which admits a variable G, is the scale covariant theory of Canuto et al. [7]. Dirac [8,9] rebuilt the Weyl's unified theory by introducing the notion of two metrics and an additional gauge function [beta]. A scale invariant variation principle was proposed from which gravitational and electromagnetic field equations can be derived. It is concluded that an arbitrary gauge function is necessary in all scale-invariant theories.
