Venue: Wisdom Village No.3

Several complex variables provides robust tools for complex/algebraic geometry, and complex/algebraic geometry provide rich problems for several complex variables. “Workshop on several complex variables and complex geometry” will focus on the fundamental material and research topics in both fields. Selected topics below are chosen for the fundamental material part; and reports on the research papers will be given in the research topic part. The depth of the fundamental material part should be suitable for master students in the relevant areas. 

Fundamental material:

1.     Positive currents and Lelong numbers.

2.     L^2 estimates, Ohsawa–Takegoshi Theorem, Skoda’s Theorem.

3.     Optimal L^2 extension.

4.     Strong openness.
