摘要：We classify all indecomposable objects in the perfect derived category of a graded skew-gentle algebra via graded curves with local system on a punctured marked surface. Furthermore, we show that the tagged intersections between graded tagged curves (with index 0) provide a basis of morphism space between the corresponding objects. This is based on my joint work with Yu Qiu and Chao Zhang.
