Connectedness and irreducibility of compact quantum groups
Alessandro D'Andrea, Claudia Pinzari, Stefano Rossi

Abstract. We show that a natural notion of irreducibility implies connectedness in the Compact Quantum Group setting. We also investigate the converse implication and show it is related to Kaplansky's conjectures on group algebras
