Title: Unitary dual problem for p-adic classical groups: the good parity case

Abstract: Classifying irreducible unitary representations is one of the most important problems in representation theory of reductive groups. In this talk, we will discuss the recent breakthrough on this problem by Atobe--Minguez, and generalize their results using the theta lifting.


Speaker: Prof. Xinyi Yuan (Beijing International Center for Mathematical Research)

Time & Venue: 16:30-17:30  MCM110

Title: A quantitative Mordell conjecture

Abstract: The Mordell conjecture was proved by Faltings in 1983, and a uniform version of the conjecture was proved by Dimitrov-Gao-Habegger and Kuhne in 2021. In tihs talk, I will present an explicit version of the uniform conjecture. This is my joint work with Jiawei Yu (虞家伟) and Shengxuan Zhou (周胜铉).
