Area preserving diffeomorphisms and Yang-Mills theory in two noncommutative dimensions

Abstract
We present some evidence that noncommutative Yang-Mills theory in two dimensions is not invariant under area preserving diffeomorphisms, at variance with the commutative case. Still, invariance under linear unimodular maps survives, as is proven by means of a fairly general argument.
