Rigidity of closed metric measure spaces with nonnegative curvature
Jia-Yong Wu
We show that one-dimensional circle is the only case for closed smooth metric measure spaces with nonnegative Bakry-Émery Ricci curvature whose spectrum of the weighted Laplacian h…

Myers' type theorem with the Bakry-Émery Ricci tensor
Jia-Yong Wu
In this paper we prove a new Myers' type diameter estimate on a complete connected Reimannian manifold which admits a bounded vector field such that the Bakry-Émery Ricci tensor ha…
