Irreducible representations of the crystallization of the quantized function algebras $C(SU_{q}(n+1))$

Abstract

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