Characterizations of generalized Robertson-Walker spacetimes concerning gradient solitons
Krishnendu De, Mohammad Nazrul Islam Khan, Uday Chand De
In this article, we examine gradient type Ricci solitons and -quasi Einstein solitons in generalized Robertson-Walker () spacetimes. Besides, we demonstrate that in thi…
Almost co-Kähler manifolds and -quasi-Einstein solitons
Krishnendu De, Mohammad Nazrul Islam Khan, Uday Chand De
The present paper aims to investigate -quasi-Einstein metrices on almost co-Kähler manifolds . It is proven that if a -almost co-Kähler manifold with $κ<…
Proposed theorems for lifts of the extended almost complex structures on the complex manifold
Mohammad Nazrul Islam Khan
The present paper aims to study the higher-order complete and vertical lifts of the extended almost complex structures on an extended complex manifold kM. The proposed theorems on…
Metallic structures on tangent bundle
Mohammad Nazrul Islam Khan
The purpose of the present work is to study the complete and horizontal lifts of the metallic structure on tangent bundles with respect to almost product structure. We also establi…
