Abstract: I will discuss a description of topological perverse sheaves on Riemann surfaces and orbifold Riemann surfaces via representations of suitable algebras. Algebras are obtained via the homotope construction from the fundamental groups of punctured Riemann surfaces. They have remarkable properties which allow to understand the perverse sheaves via ribbon graphs
