摘要
Classification theorems of locally symmetric, second-order locally symmetric, Ricci symmetric, semi-symmetric and Ricci semi-symmetric generalized Robertson-Walker (in short, GRW) spacetime I-f x N are given. Some implications for these symmetries of GRW space-times are considered. A summary of sufficient conditions on the warping function f and the fibre manifold N is given to verify each symmetry.
