Title: Laplace comparison theorem and convergence of Kähler-Ricci flows.
Abstract: We will review the classical Laplace and relative volume comparison theorems on Riemannian manifolds with Ricci curvature bounded from below. Then we will show that, after suitable conformal change, versions of these theorems persist on Kähler-Ricci flows without extra curvature assumptions. Applications to the convergence issue are also discussed. This is a joint work with G. Tian, Z. L. Zhang, M. Zhu, and X. H. Zhu.
