2024苏州几何与拓扑协作会议——学术报告
会议地点:苏州大学天赐庄校区本部精正楼306教室
报告题目:Positive scalar curvature and enlargeable foliated manifolds
报告人:苏广想(南开大学/陈省身数学研究所)
时间:2024.11.30(星期六)09:15-10:00
摘要:In this talk we first review Gromov-Lawson theorem on enlargeable manifolds and then discuss the extension to the foliated manifolds.
报告题目:From nonhyperbolic manifolds to premodular tensor categories
报告人:邱杨(南开大学/陈省身数学研究所)

摘要:In this talk, I will discuss a method to construct S,T-matrices of premodular tensor categories from some nonhyperbolic manifolds. The method is originated from physics that reveals some connection between classical topology and quantum algebra. I will show a mathematical exploration for it. The talk is based on the work joint with Xingshan Cui, Paul Gustafson, Zhenghan Wang and Qing Zhang.
报告题目:无穷体积复双曲曲面的拓扑

摘要:R. Schwartz 在2003年的论文中考虑了群G(4,7)在复双曲表示,并决定了对应的复双曲曲面的无穷远处边界流形的三维拓扑。我们证明上述群表示是单射,并搞清了这个群表示对应的复双曲曲面的四维拓扑。在此过程中,我们将柄体理论引入到复双曲曲面的研究中。这是首次清楚地了解比曲面上的平面丛更复杂的无穷体积复双曲曲面的拓扑。
