Tsinghua-BIMSA symplectic geometry seminar

Schedule:May 23, 2025 Shanon RubinTitle: A Homotopical Invariant of Weinstein SurfacesAbstract: We construct explicit models for the homotopy limits of diagrams of microlocal sheaf categories which arise from Weinstein surfaces with arboreal skeleta. This is done by characterizing all relevant Reedy model structures on the categories of diagrams that we care about. We prove invariance using a c...

YMSC Topology Seminar

Teichmuller rays, grafting rays, and isomonodromic complex projective structures on Riemann surfaces Shinpei BABA, University of Osaka* (2025-05-19)Abstract: We discuss certain relations between Riemann surface structures and representations of their fundamental groups into PSL(2,C).A CP^1-structure on a surface is an atlas of charts embedding open subsets of the surface into CP^1 such that tra...

YMSC Probability Seminar 概率论讨论班

Upcoming talks： 2025年5月15日16:00-17:00 双清综合楼C548报告人：黄瀚 (Han Huang), University of MissouriTitle: Reconstructing the Geometry of Random Geometric GraphsAbstract: Random geometric graphs are random graph models defined on metric spaces. Such a model is defined by first sampling points from a metric space and then connecting each pair of sampled points with probability that depends o...
