Abstract

In this paper, we associate a quiver with superpotential to each dd-angulation of a (unpunctured) marked surface. We show that, under quasi-isomorphisms, the flip of a dd-angulation is compatible with Oppermann's mutation of (the Ginzburg algebra of) the corresponding quiver with superpotential, thereby partially generalizing the result in [LF09]. Applying to the generalized (d2)(d-2)-cluster categories associated to this quiver with superpotential, we prove that some certain almost complete (d2)(d-2)-cluster tilting objects in the higher cluster category have exactly d1d-1 complements.
