Skew group algebras of Jacobian algebras
Abstract
For a quiver with potential with an action of a finite cyclic group , we study the skew group algebra of the Jacobian algebra . By a result of Reiten and Riedtmann, the quiver of a basic algebra Morita equivalent to is known. Under some assumptions on the action of , we explicitly construct a potential on such that . The original quiver with potential can then be recovered by the skew group algebra construction with a natural action of the dual group of . If is self-injective, then is as well, and we investigate this case. Motivated by Herschend and Iyama's characterisation of 2-representation finite algebras, we study how cuts on behave with respect to our construction.
