Symmetry and pseudosymmetry properties of Vaidya-Bonner-de Sitter spacetime
Absos Ali Shaikh, Shyamal kumar Hui, Mousumi Sarkar +1
The primary focus of the current study is to explore the geometrical properties of the Vaidya-Bonner-de Sitter (briefly, VBdS) spacetime, which is a generalization of Vaidya-Bonner…
Li-Yau, Hamilton gradient and Hessian estimates for nonlinear weighted parabolic equations and applications
Shyamal Kumar Hui, Abimbola Abolarinwa, Sujit Bhattacharyya
This article is devoted to the study of several estimations for a positive solution to a nonlinear weighted parabolic equation on a weighted Riemannian manifold. We therefore deriv…
On curvature related geometric properties of Hayward black hole spacetime
Absos Ali Shaikh, Shyamal Kumar Hui, Biswa Ranjan Datta +1
This paper is devoted to the study of curvature properties of Hayward black hole (briefly, HBH) spacetime, which is a solution of Einstein field equations (briefly, EFE) having non…
Hamilton and Souplet-Zhang type estimations on semilinear parabolic system along geometric flow
Shyamal Kumar Hui, Shahroud Azami, Sujit Bhattacharyya
In this article we derive both Hamilton type and Souplet-Zhang type gradient estimations for a system of semilinear equations along a geometric flow on a weighted Riemannian manifo…
