Stationary or static space-times and Young tableaux

Abstract

IntroductionThe subject of the present paper is the search for examples of Riemann tensors which contain terms with a structure of certain generators of algebraic curvature tensors.Let V be a finite-dimensional K-vector space, where K is the field of real or complex numbers. We denote by T r V the K-vector space of covariant tensors of order r over V .
