Jorgensen P.E.T., Schmitt L.M., Werner R.F. q--Canonical Commutation Relations and Stability of the Cuntz Algebra (56K, TeX) ABSTRACT. \let\1\sp% \def\E#1{{\cal E}\1{#1}}% \def\idty{{\bf I}}% We consider the $q$-deformed canonical commutation relations $a_ia_j\1*-q\,a_j\1*a_i= \delta_{ij}\idty$, $i,j=1,\ldots,d$, where $d$ is an integer, and $-1
