几何与拓扑讨论班——Symplectic foliation of modular Poisson structures

报告人：Zheng Hua，University of Hong Kong

Pretalk

主题：On Modular Poisson structures

时间：2025年4月7日，16:15-16:45

摘要：We will briefly recall Poisson structures in the algebraic geometry context. We will focus on two main classes of examples: moduli space of sheaves on del Pezzo surfaces and semi-classical limits of noncommutative deformations.

主题：Symplectic foliation of modular Poisson structures

时间：2025年4月7日，16:45-17:35

摘要：We will give a unified construction of the algebraic Poisson structures mentioned in the first part of the talk via moduli space of complexes on degeneration of elliptic curves. Our construction leads to a neat description of the symplectic leaves. We will discuss several applications on deformations of Hilbert schemes and positroid varieties.
