Abstract:Hilbert scheme of twisted cubics has been studied by Schlessinger and Peigne in the 1980s via explicit computation  of deformations of ideals and equations. I will talk about how to study this moduli space using Bridgeland stability condition and wall-crossing phenomenon.


  报告人介绍:夏秉禹博士,晨兴数学中心博士后,美国俄亥俄州立大学博士毕业。His research interest lies in algebraic geometry, homological algebra and deformation theory. To be more specific, I study  Bridgeland stability condition  on  the  derived  category of a  smooth projective variety and its moduli space. Via the wall-crossing phenomenon of Bridgeland stability conditions,  it is also  possible to study the birational geometry of these moduli spaces and relate them to various known moduli spaces like Gieseker moduli space of sheaves, Quot scheme or moduli of stable pair etc.
