December 1(Wednesday)2021,16:30- 18:30,via Zoom ▶Speaker : Yeansu Kim (Chonnam National University) ▶Title : Classification of discrete series representations for classical groups and GSpin groups ▶Abstract : The classification of discrete series is one main subject in Langlands program with numerous applications. We first explain the result on the...
November24(Wednesday)2021,16:30- 18:00,via Zoom ▶Speaker : Bo-Hae Im (KAIST) ▶Title : A hyperelliptic curve mapping to specified elliptic curves ▶Abstract : We consider the non-existence of rational curves on certain Kummer varieties. In particular, we prove that if the j-invariants of a 21-tuple of elliptic curves E1,…,E21 over C are algebraically independent over Q, there...
November 17 (Wednesday) 2021, 16:30 - 18:00, Building 108, Room N319 Speaker : Christian Sleek Klevdal (UNIST) Title : Integrality of G-local systems Abstract : Simpson conjectured that for a reductive group G, rigid G-local systems on a smooth projective complex variety are integral. I will discuss a proof of integrality...
November10 (Wednesday) 2021, 16:00 - 18:00, Building108, Room N319 ▶Speaker : Jungin Lee (KIAS) ▶Title : Distribution of the cokernels of random integral matrices ▶Abstract : In this talk, we consider the following questions: 1. For a random matrix A∈Mat_n(Z_p) and given finite abelian p-groups G_1 and G_2, what...
November3(Wednesday) 2021, 16:00 - 18:00,via Zoom ▶Speaker : Jun-Ho Hwang(Seoul National University) ▶Title : Decidability of integral points on some moduli spaces ▶Abstract : We discuss the Diophantine study of integral points on certain moduli spaces that arise in geometry. First, we study the integral points on moduli spaces...
