Chenyang Xu

from Wikipedia, the free encyclopedia

Chenyang Xu (* 1981 in Chongqing ) is a Chinese mathematician who studies algebraic geometry .

Xu received his PhD from Princeton University under János Kollár in 2008 (Topics on rationally connected varieties). He is a professor at the International Center for Mathematical Research in Beijing.

He deals with the Minimal Model program and birational geometry (in characteristics 0 and p), rationally connected varieties, topology of algebraic varieties, arithmetic geometry, Kähler geometry and Fano varieties. Besides Kollar, he worked with Christopher Hacon and James McKernan, among others .

In 2016 he received the ICTP Ramanujan Prize . In particular, his work on birational geometry including canonical log pairs and Q-Fano varieties as well as the topology of singularities and their dual complexes were highlighted. He is a lecturer at the ICM 2018 (Interaction Between Singularity Theory and the Minimal Model Program).
