Quadratic Differentials as Stability Conditions of Graded Skew-gentle Algebras

Abstract: We prove that the principal component of the exchange graph of hearts of a graded skew-gentle algebra can be identified with the corresponding exchange graph of S-graphs, using the geometric models and $\operatorname{Int}=\operatorname{dim}\operatorname{Hom}$ formula in Qiu-Zhang-Zhou. Using the same argument in Bridgeland-Smith, Barbieri-M\"oller-Qiu-So and Christ-Haiden-Qiu, we extend this identification to an isomorphism between the spaces of stability conditions and of quadratic differentials.
