报告题目：Group actions, equivariantization and equivariant relations among weighted projective lines

报告人：陈健敏 教授（厦门大学）

摘要：The equivariantization with respect to various finite group actions plays an important role in the study of weighted projective lines. By using group actions, one can establish the connection between weighted projective lines of tubular type and smooth elliptic curves. In this talk, I will give an introduction of group actions on a category and equivariantization of an abelian category with respect to a finite group, and then show the equivariant equivalence relations among weighted projective lines in the sense of degree-shift actions on the category of coherent sheaves.
