Abstract

In this paper we introduce the notion of Lorentzian beta-Kenmotsu manifolds We study three-dimensional Lorentzian beta-Kenmotsu manifolds satisfying Ricci-semisymmetry, locally phi-symmetry and eta-parallel Ricci tensor The existence of a locally phi-symmetry three-dimensional Lorentzian beta-Kenmotsu manifold is proved by a concrete example

It is shown that in a natural way there are precisely sixteen classes of almost Hermitian manifolds.

In this paper, we completely characterize the local structure of trans-Sasakian manifolds of dimension 5 by giving suitable examples.
