The representation type of Jacobian algebras

Understand

We show that the representation type of the Jacobian algebra P(Q,S) associated to a 2-acyclic quiver Q with non-degenerate potential S is invariant under QP-mutations.

• We prove that, apart from very few exceptions, P(Q,S) is of tame representation type if and only if Q is of finite mutation type.
• We also show that most quivers Q of finite mutation type admit only one non-degenerate potential up to weak right equivalence.
• In this case, the isomorphism class of P(Q,S) depends only on Q and not on S.
