报告题目：On surface models of coherent sheaves over weighted projective lines

时间：4月17日 (周一) 下午14:30

报告摘要： Geometric models for categories have been widely studied in recent years to gain a better understanding of the structure of the categories. Weighted projective lines are introduced by Geigle-Lenzing to give a geometric treatment to the representation theory of canonical algebras. The study of weighted projective lines is also closely related to cluster algebras, compact Riemann surfaces, Hall algebras and quantum algebras, singularity theory, GL order, and so on. In this talk, I will show our recent work on surface models for the categories of coherent sheaves over weighted projective lines.
