地点:沙河校区主楼E座E-404
摘要:In this talk I will review some classic Li-Yau estimate to the heat kernel on a manifold with Ricci curvature bounded below, then present some improvements. As the application I will also give some gradient estimate of heat kernel, with optimal leading terms comparing with the model spaces of constant curvature.
