报告摘要：

This is based on my work joint with Ping He and Bin Zhu. Skew-gentle algebras are a class of representation-tame algebras, whose indecomposable modules and morphisms can be described combinatorically. In this talk, each skew-gentle algebra is associated to a partial triangulation of a punctured marked surface. Based on this, each indecomposable module is associated to a tagged curve and each homomorphism space has a basis formed by tagged intersections. As an application, we give a geometric interpretation of support tau-tilting modules over a skew-gentle algebra.
