摘要：For any non-positive graded skew-gentle algebra, there is an associated graded punctured marked surface, such that the indecomposable objects in its perfect derived category can be realized by the graded curves with local system on the surface. Moreover, the oriented intersections of two tagged graded curves give rise to a basis of the morphism space between the corresponding objects. This is a joint work with Yu Qiu and Chao Zhang.
