We define (super) n-energy tensors for non-gravitational fields. The possibility of interchange of superenergy between gravitational and other fields is considered. 1 The Bel-Robinson tensor and its properties. The Bel-Robinson (BR) tensor 1,2 is defined by T αβλµ ≡ C αρλσ C β µ ρ σ + * C αρλσ * C β µ ρ σ (1) where C αρλσ is the Weyl tensor and * indicates the usual dual operation: * C αβλµ ≡ (...

A single spherical antenna is capable of measuring the direction and polarization of a gravitational wave. It is possible to solve the inverse problem using only linear algebra even in the presence of noise. The simplicity of this solution enables one to explore the error on the solution using standard techniques. In this paper we derive the error on the direction and polarization measurements ...

The Wheeler-DeWitt equation is solved for some scalar-tensor theories of gravitation in the case of homogeneous and isotropic cosmological models. We present general solutions corresponding to cosmological term: (i)λ(φ) = 0 and (ii)λ(φ) = qφ.
