A conformal characterization of manifolds of constant sectional curvature

Xiaoyang Chen, Francisco Fontenele, Frederico Xavier

A special case of the main result states that a complete $1$ -connected Riemannian manifold $(M^{n}, g)$ is isometric to one of the models $R^{n}$ , $S^{n} (c)$ , $H^{n} (- c)$ of…

New Bochner type theorems

Xiaoyang Chen, Fei Han

A classical theorem of Bochner asserts that the isometry group of a compact Riemannian manifold with negative Ricci curvature is finite. In this paper we give several extensions of…
