Jacobian algebras with periodic module category and exponential growth

Representation Theory 2016-03-14 v4

Abstract

The Jacobian algebra associated to a triangulation of a closed surface SS with a collection of marked points MM is (weakly) symmetric and tame. We show that for these algebras the Auslander-Reiten translate acts 2-periodical on objects. Moreover, we show that excluding only the case of a sphere with 44 (or less) punctures, these algebras are of exponential growth. These four properties implies that there is a new family of algebras symmetric, tame and with periodic module category. As a consequence of the 2-periodical actions of the Auslander-Reiten translate on objects, we have that the Auslander-Reiten quiver of the generalized cluster category \cC(S,M)\cC_{(S,M)} consists only of stable tubes of rank 11 or 22.

Comments

In the previous version I showed that the Jacobian algebras of closed surfaces, excluding the case of the sphere with 4 and 5 punctures, are algebras of exponential growth and it was changed grammar errors. In this new version I change the name of this note and I show that the Jacobian algebras of the sphere with 5 punctures are algebras of exponential growth. This is the final version
