Some Geometric Properties of Lorentzian $\beta$-Kenmotsu Manifolds Admitting $\eta$-Ricci-Yamabe Solitons

Communications in Advanced Mathematical Sciences
In this paper, we investigate the characterization of Lorentzian $\beta $-Kenmotsu manifolds admitting $\eta$-Ricci-Yamabe solitons. First, we examine the cases where such manifolds are Ricci pseudosymmetric and Ricci semisymmetric.

On the Ricci Curvature of Normal-Metric Contact Pair Manifolds

Journal of New Theory, 2021
In this study, we work on normal-metric contact pair manifolds under certain conditions related to the Ricci curvature. We obtain some results for generalized quasi-Einstein normal-metric contact pair manifolds.

On area comparison and rigidity involving the scalar curvature [PDF]

In this thesis we study the effects of lower bounds for the curvature of a Riemannian manifold M on the geometry and topology of closed, minimal hypersurfaces.

Coxeter groups, graphs and Ricci curvature

, 2020
We consider a notion of curvature for graphs introduced in 1998 by Schmuckenschläger which is an analogue of Ricci curvature. First of all we see some general results on the discrete Ricci curvature of any locally finite graph.

Closed time-like curves in f(R,A) modified gravity theory

Nuclear Physics B
In this manuscript, we investigate solutions that allow closed time-like curves (CTCs) in general relativity (GR) within the framework of a modified gravity theory. We consider here an alternative theory recently proposed in gravity theories known as f(R,
