Title: Symmetries of varieties Venue: 北京国际数学研究中心 镜春园82号甲乙丙楼 82J12教室 Time: 16 Jul 2012 16:30-17:30 Speaker: James McKernan (MIT) Abstract: We describe old and new work on the symmetries of polynomials and their zeroes. In particular we focus on two extreme cases. If the automorphism group is large, it is interesting to try to give explicit generators of the automorphism group. If the automorphism group is small, it is interesting to give uniform bounds on the order of the automorphism group.
