题 目：On certain surfaces of general type with geometric genus zero and Bloch conjecture
时 间：2021.6.23（星期三），14:45-15:45
地 点：思源楼 817
摘 要：I will give a brief introduction to complex smooth surfaces of general type with geometric genus zero. A complete classification of such surfaces is still missing and it is quite hard to construct examples. I will about several families of smooth surfaces of general type with invariants p_g = 0 and K^2 = 7. One of which is recently constructed by Y. Shin and myself. Then I will discuss their bicanonical maps, automorphism groups, moduli spaces and Bloch conjecture for these surfaces.

题 目：Minimal log discrepencies and termination of flips
时 间：2021.6.24（星期四），19:00-20:30
地 点：思源楼 817
摘 要：I will give a brief introduction to minimal log discrepencies and flips. Then I will introduce the work of Shokurov: ACC conjecture for mld amended with their semicontinuity conjecture due to Florin Ambro implies that termination of flips.
