题 目: Bundles over rational surfaces and Weierstrass cubics
报告人: 张加劲 四川大学
时 间: 9月23日 星期一 下午2:00 � 3:30
地 点: 管理科研楼1611会议室
摘 要: This work in progress is joint with Naichung Conan Leung. In this talk, we shall study principal G-bundles over certain rational surfaces S, and describe the relation between the moduli space of the surfaces S, containing D as a possibly singular anti-canonical curve, and the moduli space of certain principal G-bundles over D. We show that these two moduli spaces are isomorphic to each other. When D is singular (nodal or cuspidal Weierstrass cubics), moduli spaces considered here are in fact affine spaces, whose compactifications are very interesting.
