Abstract
Let K be a field and q be a nonzero element of K that is not a root of unity. We give a criterion for (0) to be a primitive ideal of the algebra Oq(Mm,Mn) of quantum matrices. Next, we describe all height one primes of these two problems are actually interlinked since it turns out that (0) is a primitive ideal of Oq(Mm,Mn) whenever Oq(Mm,Mn) has only finitely many height one primes. Finally, we compute the automorphism group of Oq(Mm,Mn) in the case where m not equal n. In order to do this, we first study the action of this group on the prime spectrum of Oq(Mm,Mn). Then, by using the preferred basis of Oq(Mm,Mn) and PBW bases, we prove that the automorphism group of Oq(Mm,Mn) is isomorphic to the torus (K*)(m+n=1) when m not equal n and (m, n) not equal (1, 3) (3, 1).
