Description
Summary:We develop a unified approach for identifying spaces of stability conditions of triangulated categories arising from weighted marked surfaces with moduli spaces of quadratic differentials. This approach is based on the notion of a perverse schober (perverse sheaf of triangulated categories) and their triangulated categories of global sections. Under suitable conditions on the perverse schober, we identify mixed-angulations and their flips with finite-length hearts and their tilts, which then leads to the identification of moduli spaces. As an application we obtain a generalization of the results of Bridgeland--Smith to quadratic differentials with arbitrary singularity type (zero/pole/exponential).
