A Lefschetz fixed-point formula for certain orbifold C*-algebras

Siegfried Echterhoff, Heath Emerson, Hyun Jeong Kim

Using Poincaré duality in K-theory, we state and prove a Lefschetz fixed point formula for endomorphisms of cross product C*-algebras $C_0(X)\cross G$ coming from covariant pairs.…

Inheritance of Isomorphism Conjectures under colimits

Arthur Bartels, Siegfried Echterhoff, Wolfgang Lueck

We investigate when Isomorphism Conjectures, such as the ones due to Baum-Connes, Bost and Farrell-Jones, are stable under colimits of groups over directed sets (with not necessari…
