• K-Theory for Group C*-Algebras and Semigroup C*-Algebras 

      [OWS-47] Cuntz, Joachim; Echterhoff, Siegfried; Li, Xin; Yu, Guoliang (Birkhäuser Basel, 2017)
      This book gives an account of the necessary background for group algebras and crossed products for actions of a group or a semigroup on a space and reports on some very recently developed techniques with applications to ...
    • Topological and Bivariant K-theory 

      [OWS-36] Cuntz, Joachim; Meyer, Ralf; Rosenberg, Jonathan M. (Birkhäuser Basel, 2007)
      Topological K-theory is one of the most important invariants for noncommutative algebras equipped with a suitable topology or bornology. Bott periodicity, homotopy invariance, and various long exact sequences distinguish ...
