General Relativistic Space-Time with η1-Einstein Metrics

Y Li, F Mofarreh, S Dey, S Roy, A Ali - Mathematics, 2022 - mdpi.com
The present research paper consists of the study of an η 1-Einstein soliton in general
relativistic space-time with a torse-forming potential vector field. Besides this, we try to …

Almost conformal Ricci solitons on generalized Robertson–Walker space-times

SK Yadav, DL Suthar, SK Chaubey - Research in Mathematics, 2023 - Taylor & Francis
The goal of this paper is to investigate almost conformal Ricci solitons on extended
Robertson–Walker and standard static space-times in terms of conformal vector fields …

A Note on Shape Vector Fields on Hypersurfaces

SB Al-Shaikh - Symmetry, 2023 - mdpi.com
In this paper, we initiate the study of shape vector fields on the hypersurfaces of a
Riemannian manifold. We use a shape vector field on a compact hypersurface of a …

Some New Results on Trans‐Sasakian Manifolds

L Wang, Y Zhao - Journal of Mathematics, 2022 - Wiley Online Library
In this paper, we classify trans‐Sasakian manifolds which are realized as real hypersurfaces
in a complex space form. We also investigate trans‐Sasakian manifolds whose Reeb vector …
