Title: On (n-2)-connected 2n-dimensional Poincare complexes
Time&Venue: 2024年11月20日（星期三） 15:15-16:15 & 南楼N818
Abstract: Poincare complexes, roughly speaking, are CW complexes which satisfy Poincare duality for arbitrary local coefficients. They share many similar properties with manifolds. In this talk, I will focus on (n-2)-connected 2n-dimensional Poincare complexes with torsion-free homology. I will discuss their classification, and compare our results with known results concerning (n-2)-connected 2n-manifolds.
