Title:Surfaces on the Severi line in positive characteristic
Biography:
Dr. Yi Gu obtained his PhD from Peking University in 2015. Now he is an associate professor in Soochow University. His research interest is algebraic geometry.
Abstract:
Let X be a minimal surface of general type with maximal Albanese dimension. It is proved by Pardini in characteristic zero and by Yuan-Zhang in positive characteristic that the following inequality:
holds. We say X is on the Severi line of the equality holds. In characteristic zero, a classification of surfaces on the Severi line is given by Barja-Pardini-Stoppino and Lu-Zuo independently. In this talk, we will present a classification of surface on the Severi line in positive characteristic. This is a joint work with Professor X. Sun and M. Zhou.
