摘要：We first introduce Arthur's formula for L^2 Lefschetz numbers of Hecke operators, and show it can be interpolated p-adically. For a reductive group which is anisotropic at infinite, we then give an explicit formula for twisted Lefschetz numbers and show it can also be interpolated p-adically.
Those p-adic interpolations give a p-adic trace formula theory parallel to the theory of Arthur-Clozel.

He obtained his PhD degree in Mathematics from Columbia University, where he studied p-adic automorphic forms and eigenvariety theory under the advisor of Professor Eric Urban. He was a Hedrick assistant professor in UCLA and worked with Professor Haruzo Hida. Now he is a young investigator at Fudan University, Shanghai Center for Mathematical Science.
His research interests include Number Theory, p-adic automorphic forms and p-adic trace formulas.
