Some Types of Weakly Ricci Symmetric Riemannian Manifolds
Payel Karmakar, Arindam Bhattacharyya
In this paper we discuss when a quasi-conformally flat weakly Ricci symmetric manifold (of dimension greater than 3) becomes a manifold of hyper quasi-constant curvature, a quasi-E…

CR-submanifolds of Some Lorentzian Manifolds and K-manifolds
Payel Karmakar
In this paper I have studied about CR(Cauchy-Riemann)-submanifolds of Lorentzian Concircular Structure manifold ((LCS)n-manifold), Lorentzian Para-Sasakian(LP)-cosymplectic manifol…
