Abstract

Crystallization of the CC^*-algebras C(SUq(n+1))C(SU_{q}(n+1)) was introduced by Giri \& Pal as a CC^*-algebra C(SU0(n+1))C(SU_{0}(n+1)) given by a finite set of generators and relations. Here we study representations of the CC^*-algebra C(SU0(n+1))C(SU_{0}(n+1)) and prove a factorization theorem for its irreducible representations. This leads to a complete classification of all irreducible representations of this CC^*-algebra. As an important consequence, we prove that all the irreducible representations of C(SU0(n+1))C(SU_{0}(n+1)) arise exactly as q0+q\to 0+ limits of irreducible representations of C(SUq(n+1))C(SU_{q}(n+1)). We also present a few other important corollaries of the classification theorem.
