Quantum group-twisted tensor products of C*-algebras
Ralf Meyer, Sutanu Roy, Stanislaw Lech Woronowicz
We put two C*-algebras together in a noncommutative tensor product using quantum group coactions on them and a bicharacter relating the two quantum groups that act. We describe thi…

Crossed products for actions of crossed modules on C*-algebras
Alcides Buss, Ralf Meyer
We decompose the crossed product functor for actions of crossed modules of locally compact groups on C*-algebras into more elementary constructions: taking crossed products by grou…

An equivariant Lefschetz fixed-point formula for correspondences
Ivo Dell'Ambrogio, Heath Emerson, Ralf Meyer
We compute the trace of an endomorphism in equivariant bivariant K-theory for a compact group G in several ways: geometrically using geometric correspondences, algebraically using…
