报告摘要:
In this talk, we provide a geometric realization of exceptional sequences in the category of coherent sheaves over the weighted projective line of type (p, q). As applications, a classification of complete exceptional sequences, an effective method for enlarging exceptional sequences and a combinatorial description of tilting bundles are obtained. Consequently, the number of tilting bundles up to the Auslander-Reiten translation is given. This is a joint work with Yiting Zheng.
