报告摘要：We give a full description of graded gentle algebras (which are not necessarily homologically smooth or proper) whose perfect derived categories admit silting objects. We apply this to determine which graded gentle algebras admit pre-silting objects that are not partial silting. As the second application, we give a complete invariant for graded gentle algebras, which confirm a conjecture by Lekili and Polishchuk. This talk is based on a work joint with Sibylle Schroll and Zhengfang Wang.
