Concircular curvature on warped product manifolds and applications
Uday Chand De, Sameh Shenawy, Bulent Unal
This study aims mainly at investigating the effects of concircular flatness and concircular symmetry of a warped product manifold on its fibre and base manifolds. Concircularly fla…

On generalized quasi-Einstein GRW space-times
Uday Chand De, Sameh Shenawy
Recently, it is proven that generalized Robertson-Walker space-times in all orthogonal subspaces of Gray's decomposition but one(unrestricted) are perfect fluid space-times. GRW sp…

On Interpolating Sesqui-Harmonic Legendre Curves in Sasakian Space Forms
Fatma Karaca, Cihan Özgür, Uday Chand De
We consider interpolating sesqui-harmonic Legendre curves in Sasakian space forms. We find the necessary and sufficient conditions for Legendre curves in Sasakian space forms to be…
