Recently, the 2024 Geometry & Topology Conference, organized by ShanghaiTech University, was held in Qingtian County, Zhejiang Province. The conference focused on the latest advances in aspects of geometry and topology, attracting more than 70 experts from countries including China, France, Germany, Japan, and the United States.
Assistant Professor Wang Shi from the Institute of Mathematical Sciences (IMS) at ShanghaiTech University presided over the opening ceremony.

Pan Wei, Chief of Qingtian County, Kuang Shizhong, Chair of the Association for Science and Technology of Lishui City, and Tu Junwu, Assistant Director of IMS, delivered speeches at the conference.
Tu said that the conference showcased the forefront of research in the field of mathematical sciences and was an excellent opportunity to inspire innovative thinking and promote academic cooperation and exchanges, fostering progress in the fields of geometry and topology.
The conference featured 16 plenary speakers from institutions including the Chern Institute of Mathematics at Nankai University, Harvard University, Stanford University, Karlsruhe Institute of Technology (KIT), and others. Topics covered various areas of interest, including moduli spaces, Kähler geometry, geometric analysis, low-dimensional topology, and geometric group theory.
Dr. Wilderich Tuschmann from KIT presented a report titled “Spaces and moduli spaces of (Riemannian) metrics,” discussing important advances in the geometric and topological properties of moduli spaces of nonnegatively curved Riemannian metrics on manifolds.
Dr. Li Qiongling from the Chern Institute discussed her latest research results on the index and total curvature of minimal surfaces in noncompact symmetric spaces and wild harmonic bundles.
Dr. Gao Hongbao from Tsinghua University presented the recent advances on Legendrian knots and their exact Lagrangian fillings.
Dr. Shouhei Honda from the University of Tokyo reported a couple of rigidity results on flat tori in terms of harmonic maps. Dr. Liu Beibei from Ohio State University talked about the uniform convergence of hyperbolic manifolds and its applications in counting the number of simple closed geodesics and othogeodesics. Dr. Wu Xiaolei from the Shanghai Center for Mathematical Sciences discussed how one could calculate the homology of big mapping class groups of some well-known surfaces, including disk minus a Cantor set, while Dr. He Siqi from the Chinese Academy of Sciences lectured on ℤ2 harmonic spinors and 1-forms.
