Classification of Weyl and Ricci Tensors

, 2016
The theory of General Relativity was formulated by Albert Einstein and introduced a set of equations: Einstein field equations. Since then, many exact solutions of these equations have been found. An important result in the study of exact solutions to Einstein equations is the classification of space-times according to the Weyl tensor (Petrov ...
