Abstract

For CC^*-algebra generated by a finite family of isometries sjs_j, j=1,,dj=1,\dots,d satisfying qijq_{ij}-commutation relations sjsj=I,sjsk=qijsksj,qij=qˉji,qij<1, 1ijd, s_j^* s_j = I, \quad s_j^* s_k = q_{ij}s_ks_j^*, \qquad q_{ij} = \bar q_{ji}, |q_{ij}|<1, \ 1\le i \ne j \le d, we construct an infinite family of unitarily non-equivalent irreducible representations. These representations are deformations of the corresponding class of representations of the Cuntz algebra Od\mathcal O_d.
