NT Seminar TOMORROW: Wanlin Li

[Bianca Viray]

Hi all,

Our first seminar of the quarter will be tomorrow (Tuesday, October 22) at 11am in PDL C-401. Our speaker is Wanlin Li from Washington University in St. Louis and she will be speaking on Non-vanishing of Ceresa and Gross--Kudla--Schoen cycles (abstract below). As usual, we will go to lunch with the speaker after the seminar.

Abstract: The Ceresa cycle and the Gross—Kudla—Schoen modified diagonal cycle are algebraic 1-cycles associated to a smooth algebraic curve. They are algebraically trivial for a hyperelliptic curve and non-trivial for a very general complex curve of genus >2. Given an algebraic curve, it is an interesting question to study whether the Ceresa and GKS cycles associated to it are rationally or algebraically trivial. In this talk, I will discuss some methods and tools to study this problem.
