Seminar in Algebraic Geometry 主講者: Professor Shin-Yao Jow(賓州大學) 講題: Effective cone of the space of maps from $P^1$ to a Grassmannian 時間: 2012-03-06 (Tue.)  11:00 - 12:00 地點: 數學所 617 研討室 (台大院區) Abstract: We will describe the effective cone of the Quot scheme which compactifies the space of maps from $P^1$ to a Grassmannian. This space has seen some applications in enumerative geometry and mathematical physics, and determining its effective cone is a first step in understanding its birational geometry. || Close window ||
