Algebras derived equivalent to skew-gentle algebras (English)
[ Abstract ]
The class of gentle algebras has several nice properties: its derived categories are well understood, it has deep connections with surface geometry, and it is closed under derived equivalence. A generalized class of skew-gentle algebras also has well-behaved derived categories and a geometric model. However, the class of skew-gentle algebras is not closed under derived equivalence. In this talk, we introduce a larger class of semi-gentle algebras with a geometric model and talk about closedness of the class under derived equivalence. This is a joint work with Severin Barmeier, Cheol-Hyun Cho, Kyungmin Rho, Sibylle Schroll, and Zhengfang Wang.
