Spectre de l'alg\`ebre de Weyl quantique
Laurent Rigal
Abstract.
In this paper, we classify the prime spectrum of the quantized Weyl algebra
$A_{n}^{\bar{q},\Lambda}$
arising from the quantum differential calculus of G.\ Maltsiniotis
on the quantum multiparameter space.
$A_{n}^{\bar{q},\Lambda}$ is an algebra of differential operators on this space. It is shown that the set of non-maximal prime ideals is finite of
cardinality
${1\over 2}[(2 + \sqrt{2})^n+(2 - \sqrt{2})^n]$.
As a consequence, we prove that
$A_{n}^{\bar{q},\Lambda}$
is catenary. We also describe explicitly the automorphism group of this algebra.
