报告标题：Cohomological rank functions and algebraic surfaces of general type

摘要：

In this talk,wewill first recall basic and well-known geographical inequalities for algebraic surfaces of general type. Then talk about generic vanishing theory, cohomological rank function and eventual paracanonical map. It turns out that the cohomological rank functions provide enough information to a fine classification for surfaces of general type with small invariants. This is based on a joint work with Zhi Jiang and Guoyun Zhang.
