The object of the present paper is to study the invariant submanifolds of (LCS)n-manifolds. We study semiparallel and 2-semiparallel invariant submanifolds of (LCS)n-manifolds. Among others we study 3-dimensional invariant submanifolds of (LCS)n-mani

In this article, we have introduced the concept of \textit{geodesic $(\alpha,E)$-invex set} and by using this concept the notion of \textit{geodesic $(\alpha,E)$-preinvex functions} and \textit{geodesic $(\alpha,E)$-invex functions} are developed on

In this paper, we have studied the striction curves of a normal ruled surface. We have shown that the evolute of a base curve is the striction curve of a normal ruled surface and the singularities of such surface lie on the evolute of the base curve.

The paper aims to investigate curvature inheritance symmetry in M-projectively flat spacetimes. It is shown that the curvature inheritance symmetry in M-projectively flat spacetime is a conformal motion. We have proved that M- projective curvature te

The aim of this paper is to study the geometric properties of the point-like global monopole (briefly, PGM) spacetime, which is a static and spherically symmetric solution of the Einstein's field equations. It has shown that PGM spacetime admits vari

In this paper, we have investigated some aspects of gradient $$\rho$$ -Einstein Ricci soliton in a complete Riemannian manifold. First, we have proved that the compact gradient $$\rho$$ -Einstein soliton satisfying some curvature conditions is isomet

The main objective of the present paper is to investigate the curvature properties of generalized pp-wave metrics. It is shown that a generalized pp-wave spacetime is Ricci generalized pseudosymmetric, 2-quasi-Einstein and generalized quasi-Einstein
