报告摘要：We first prove a Hamilton-Souplet-Zhang type gradient estimate for the heat equation on Riemannian manifolds satisfying certain integral Ricci curvature condition. Then as an application, by implanting the Hamilton-Souplet-Zhang type estimate in an argument of Qi S. Zhang, we show that certain integral Li-Yau inequality holds for the heat equation in this circumstance. This is a joint work with Xingyu Song, Ling Wu, and Qi S. Zhang.
