Abstract

Go to

In this note we show that Lorentzian Concircular Structure manifolds $(LCS)_n$ coincide with Generalized Robertson-Walker space-times.

Keywords: Generalized Robertson-Walker space-time, Lorentzian concircular structure, torse-forming vector, concircular vector

MSC numbers: Primary 53B30; Secondary 53C25
