Liyuan Scholars Colloquium Session 161

Title:  From Tight Riemann Surfaces to Three-Dimensional Clusters—A Microcosm of Biholistic Geometry's Evolution

Speaker: Professor Meng Chen (Fudan University)

Time: 16:00–17:00, January 16, 2026

Location: Room 2, Huixing Building, Yuehai Campus, Shenzhen University

Abstract:  This lecture traces the evolution of birational geometry from algebraic curves to algebraic surfaces and higher dimensions. The latter part explores current research on three-dimensional algebraic varieties following the minimal model program, focusing on their canonical birational geometry, geometric classification, and moduli space studies.

Speaker Profile: Meng Chen is a Distinguished Professor at Fudan University and Chief Professor at the Shanghai Mathematical Center. He serves as a member and secretary-general of the 8th Mathematics Discipline Review Panel under the Academic Degrees Committee of the State Council, Director of the Key Laboratory of Nonlinear Mathematical Models and Methods under the Ministry of Education, and Deputy Editor-in-Chief and Editorial Director of the Annals of Mathematics. He previously served as Dean of the School of Mathematical Sciences at Fudan University and President of the Shanghai Mathematical Society. Research Focus: Algebraic geometry. Conducted postdoctoral research at the International Centre for Theoretical Physics (ICTP) in Italy and the University of Göttingen in Germany from 1998 to 2000. Specializes in the birational geometry of algebraic varieties. Representative research includes establishing the canonical classification theory for three-dimensional algebraic varieties, discovering and proving the Noetherian type inequality for three-dimensional varieties, and achieving significant breakthroughs in the refined birational geometry and topological problems of higher-dimensional varieties. To date, he has published 63 academic papers. Currently serves as the principal investigator for the National Natural Science Foundation of China's Innovative Research Group Program. Invited to deliver a 45-minute lecture at the 2018 International Congress of Mathematicians. Recipient of the National Science Fund for Distinguished Young Scholars and selected for the National High-Level Talent Program. Awarded the First Prize of the Ministry of Education's Natural Science Award and the Silver Prize of the Morningside Prize in Mathematics.
