报告摘要
In this talk, we first discuss weighted mean curvature and volume comparisons on smooth metric measure space under the integral Bakry–Emery Ricci tensor bounds. In particular, we add an additional condition on the potential function to ensure the validity of previous conclusions for some cases proved by Prof. Jiayong Wu. Then, we apply the comparison results to get a new diameter estimate and a fundamental group finiteness under the integral Bakry–Emery Ricci tensor bounds. This is a joint work with Prof. Yu Zheng and Jiayong Wu.
