The First Eigenvalue of $P$ -manifolds

Akhil Ranjan, G. Santhanam

Antonio Ros gave a lower bound for the first eigenvalue $λ_{1}$ of $Δ$ of a $P$ -manifold $(M, g)$ in terms of the lower bound on the Ricci curvature $R i c_{M}$ and asked what happened w…

A Generalisation of Obata's theorem

Akhil Ranjan, G. Santhanam

In a complete Riemannian manifold $(M, g)$ if the hessian of a real valued function satisfies some suitable conditions then it restricts the geometry of $(M, g)$ . In this paper we…
