Title: Igusa stacks and cohomology of Shimura varieties Abstract: Cohomology of Shimura varieties has drawn interest from number theory and representation theory. Following ideas developed by Caraiani-Scholze, Koshikawa, Santos, Hamann-Lee, I will explain how vanishing type of results for the generic part in the cohomology of Shimura varieties with torsion coefficients can be obtained, using […]
