Title: Cusp K\"ahler-Ricci flows on K\"ahler manifolds

Abstract: In this report, I will talk about the long-time existence and uniqueness of cusp K\"ahler-Ricci flows on K\"ahler manifold M which carries a smooth divisor D such that the twisted canonical bundle K_M+D is ample. Furthermore, we prove that this flow converge to the unique cusp K\"ahler-Einstein metric.

下午第二个报告：刘世平（中科大）

Time:14:45~15:45

Title: Ricci curvature and eigenvalue estimates for discrete and continuous magnetic Laplacian

Abstract: We present Lichnerowicz type estimates and (higher order) Buser type estimates for the magnetic Laplacian on discrete graphs with signatures and on closed Riemannian manifolds with magnetic potentials. These results relate eigenvalues, magnetic fields, Ricci curvature and Cheeger type constants. This is based on joint work with Michela Egidi,

Florentin M\"unch, and Norbert Peyerimhoff.
