Almost coKähler manifolds in the context of mixed Killing vector field

Paritosh Ghosh

A vector field $V$ on any (semi-)Riemannian manifold is said to be mixed Killing if for some nonzero smooth function $f$ , it satisfies $L_{V} L_{V} g = f L_{V} g$ , where $L_{V}$ is the Lie deriv…

Some Characteristics of Almost $ω$ -Bach Solitons

Paritosh Ghosh, Hemangi Madhusudan Shah, Arindam Bhattacharyya

In this article, we introduce $ω$ -Bach tensor corresponding to one form $ω$ and correspondingly introduce almost $ω$ -Bach solitons, thereby generalizing the existing notion of Bach…

Quasi-isometry between two almost contact metric manifolds

Arindam Bhattacharyya, Dipen Ganguly, Paritosh Ghosh +1

In this paper the notion of quasi-isometry between two Riemannian manifolds has been introduced. This idea is also imposed to study quasi-isometry between two almost contact metric…
