Title: Cohomological descent for local-global obstructions
Speaker: Chang Lv(Institude of Information Engineering, Chinese Academy of Sciences)
Time: 7.27(Monday), 14:00-15:00
Venue: Mingde Building B201-1
Abstract: I will start by giving the basic construction of the infinite category encoding local-global obstructions, using Liu-Zheng's six-functor formalizm. Then I will show the cohomological descent and use it to deduce some new obstructions and their properties.
