Enhanced six operations on Artin stacks W. Zheng |
|||
Аннотация: Analogues of Grothendieck's six operations for étale cohomology of Artin stacks have been considered by Behrend, Laszlo, Olsson and others. In a recent joint work with Yifeng Liu, we give a general construction of the six operations and prove the base change theorem. After recalling some background, I will explain how higher category theory plays an essential role in our work. Язык доклада: английский |
