Abstract
We consider quiver algebras A q over a field k defined by two cycles and a quantum-like relation depending on a nonzero element q in k. We determine the Hochschild cohomology ring of A q and give necessary and sufficient conditions for A q to have the finitely generated Hochschild cohomology ring.
