On semi-Quasi-Einstein Manifold
Yanling Han, Avik De, Peibiao Zhao
In the present paper we introduce a semi-quasi-Einstein manifold from a semi symmetric metric connection. Among others, the popular Schwarzschild and Kottler spacetimes are shown t…
A classification of conformally flat generalized Ricci recurrent pseudo-Riemannian manifolds
Avik De, Loo-Tee How
Conformally flat pseudo-Riemannian manifolds with generalized Ricci recurrent, structure are completely classified in this short report. A conformally flat generalized Ric…
Generalized Sasakian space forms and Riemannian manifolds of quasi constant sectional curvature
Avik De, Tee-How Loo
In this paper, we show that a generalized Sasakian space form of dimension greater than three is either of constant sectional curvature; or a canal hypersurface in Euclidean or Min…
Real hypersurfaces with pseudo-parallel normal Jacobi operator in complex two-plane Grassmannians
Avik De, Tee-How Loo
The objective of the present paper is to prove the non-existence of real hypersurface with pseudo-parallel normal Jacobi operator in complex two-plane Grassmannians. As a corollary…
