Prof. LIU Yifeng wins the 2025 Alexanderson Award

Recently, Professor LIU Yifeng of the Institute for Advanced Study in Mathematics at Zhejiang University and his collaborators—Raphaël Beuzart-Plessis (University of Aix-Marseille), TIAN Yichao (Chinese Academy of Sciences), XIAO Liang (Peking University), ZHANG Wei (MIT), and ZHU Xinwen (Stanford University)—received the 2025 Alexanderson Award.

The team was honored for its work through the American Institute of Mathematics (AIM) SQuaREs project, “Geometry of Shimura varieties and arithmetic application to L-functions.” The award recognizes two papers: “Isolation of the cuspidal spectrum, with applications to the Gan-Gross-Prasad conjecture” by Beuzart-Plessis, LIU, ZHANG, and ZHU, published in the Annals of Mathematics in 2021; and On the Beilinson-Bloch-Kato conjecture for Rankin-Selberg motives” by LIU, TIAN, XIAO, ZHANG, and ZHU, published in Inventiones Mathematicae in 2022.

On behalf of the team, Professor LIU Yifeng also delivered the AIM Alexanderson Award Lecture titled “From periods of modular forms to arithmetic geometry.”

Established by AIM, the Alexanderson Award is awarded annually to recognize outstanding research published within the past three years that are based on AIM’s SQuaREs research program. The award is presented at the Joint Mathematics Meetings (JMM) each January.

In recent years, Professor LIU Yifeng and his collaborators have solved a series of prominent problems in number theory. He received the 2017 Sloan Research Fellowship and the 2018 SASTRA Ramanujan Prize, attracting wide international attention. In 2021, after resigning from his tenured full professorship at Yale University, he returned to China and joined Zhejiang University full-time as a professor and Ph.D. supervisor at the Institute for Advanced Study in Mathematics. He currently serves as Executive Vice Dean of the School of Mathematical Sciences at Zhejiang University. His research focuses on algebraic number theory, automorphic forms, and algebraic geometry.
