Continuing the analysis in [19, 5], we give purely algebraic characterization of the canonical endomorphism in interesting infinite index cases. We apply these results when compact and discrete (but not necessarily finite dimensional) Woronowicz algebras [22] act alternately on the factors in the various levels of Jones’ tower. We characterise when the acting algebra is a Kac algebra. Mathematics Subject Classification Numbers: Primary 46L37, Secondary 46L05.
