ON 3-DIMENSIONAL LORENTZIAN CONCIRCULAR STRUCTURE MANIFOLDS

摘要

The aim of the present paper is to study the Eisenhart prob- lems of finding the properties of second order parallel tensors (symmetric and skew-symmetric) on a 3-dimensional LCS-manifold. We also inves- tigate the properties of Ricci solitons, Ricci semisymmetric, locally φ- symmetric, η-parallel Ricci tensor and a non-null concircular vector field on (LCS) 3 -manifolds.
