Ma Jiming (Fudan University)
Title：Schwartz's complex hyperbolic surface
Abstruct：In this talk, we show the representation G(4,7)→Γ(4,7) is faithful, and determine the 4-dimensional topology of the complex hyperbolic surface H via the handle structure.
Lv Zhi (Fudan University)
Title：A simple introduction on Hopf conjecture
Abstract：In this talk, we give a simple introduction of the Hopf conjecture.
Li Youlin (Shanghai Jiao Tong University)
Title：Existence of fillable contact structure on 3-manifolds
Abstract：In this talk, more hyperbolic 3-manifolds admitting no symplectic fillable contact structure are given. All these 3-manifolds are obtained by surgeries along knots or links.
Organizer：School of Mathematical Science
Students and teachers who are interested are welcome.
