ABSTRACT Let k be a field, and a -dimensional quantum torus parametrized by a matrix Λ with entries in k*. The main object of this paper is to prove that, if is simple, then any k-algebra endomorphism of is surjective (and therefore is an automorphism). We use this result to prove that some quantum polynomial algebras are isomorphic if and only if they are rationally equivalent. In the case where is not simple, we give a condition for a k-algebra endomorphism of to be an automorphism.
