"Modulations and potentials for triangulated surfaces" by Jan Geuenich (Bielefeld)

Triangulations of surfaces with marked points and weighted orbifold points encode the mutation combinatorics of "almost all" cluster algebras of finite mutation type. From a representation-theoretic point of view, Jacobian algebras of triangulations play a key role. Daniel Labardini Fragoso defined and investigated these algebras for surfaces without orbifold points. In joint work with him we extend this theory to surfaces that may have weighted orbifold points. The natural set-up for this generalization are modulations for weighted quivers.
