Title: AI for moduli of differentials时间和地点：2026年8月7日，周五下午1:30-2:30，教室双清c654主讲人：陈大卫，波士顿学院邀请人：邱宇Abstract: Differentials on Riemann surfaces correspond to translation surfaces with cone points, where the zero orders of differentials determine the cone angles of translation surfaces. Affine transformation acts on translation surfaces and preserves the zero type...

Learning seminar on semistable Higgs bundles in positive characteristic

Abstract: In complex geometry, the nonabelian Hodge correspondence relates complex representations of the fundamental group of a smooth projective algebraic variety to semistable Higgs bundles with vanishing Chern classes. Its proof, however, relies essentially on analytic methods, including harmonic metrics and partial differential equations. In p-adic geometry, Faltings, Heuer, and others hav...

Analysis & PDE Seminar

Upcoming Talk: Title: Internal waves and circle homeomorphismsAbstract: Internal waves are gravity waves that propagate within density-stratified fluids and play a fundamental role in geophysical and astrophysical fluid dynamics. The spectral and evolution theories of internal waves are related to circle homeomorphisms, sometimes referred to as "ch...

Tsinghua-BIMSA symplectic geometry seminar

Schedule:2026/07/13 4:50-5:50 pm, Shuangqing 725Yash DeshmukhTitle: A categorical CohFTAbstract: Costello and Caldararu-Tu constructed categorical enumerative invariants associated to a smooth and proper Calabi-Yau category equipped with a splitting of the non-commutative Hodge-de Rham spectral sequence. I will discuss an extension of this to a chain-level cohomological field theory (CohFT) str...
