Wei Zhang: Diagonal cycles: some results and conjectures (NTWS 191)
Channel: Number Theory Web Seminar
Date: 2023-12-02

Abstract: Algebraic cycles are among the most fundamental mathematical objects. I will discuss a class of special algebraic cycles related to the diagonal cycle, including the Gross-Schoen cycle (the small diagonal) on the triple product of a curve, the arithmetic diagonal cycle appearing in the Gan-Gross-Prasad conjecture, as well as the Fourier-Jacobi cycle defined by Yifeng Liu.
