    Noncommutative topological entropy of endomorphisms of Cuntz algebras
    (Oberwolfach : Mathematisches Forschungsinstitut Oberwolfach, 2008) Skalski, Adam; Zacharias, Joachim
    Noncommutative topological entropy estimates are obtained for ‘finite range’ endomorphisms of Cuntz algebras, generalising known results for the canonical shift endomorphisms. Exact values are computed for a class of polynomial endomorphisms related to branching function systems introduced and studied by Bratteli, Jorgensen and Kawamura.
