On Exel-Pardo algebras
Erik Bédos, S. Kaliszewski, John Quigg
We generalize a recent construction of Exel and Pardo, from discrete groups acting on finite directed graphs to locally compact groups acting on topological graphs. To each cocycle…
Dualities for maximal coactions
S. Kaliszewski, Tron Omland, John Quigg
We present a new construction of crossed-product duality for maximal coactions that uses Fischer's work on maximalizations. Given a group and a coaction we define a gen…
Exact large ideals of B(G) are downward directed
S. Kaliszewski, Magnus B. Landstad, John Quigg
We prove that if E and F are large ideals of B(G) for which the associated coaction functors are exact, then the same is true for the intersection of E and F. We also give an examp…
Coaction functors
S. Kaliszewski, Magnus B. Landstad, John Quigg
A certain type of functor on a category of coactions of a locally compact group on C*-algebras is introduced and studied. These functors are intended to help in the study of the cr…
Properness conditions for actions and coactions
S. Kaliszewski, Magnus B. Landstad, John Quigg
Three properness conditions for actions of locally compact groups on C*-algebras are studied, as well as their dual analogues for coactions. To motivate the properness conditions f…
Destabilization
S. Kaliszewski, Tron Omland, John Quigg
This partly expository paper first supplies the details of a method of factoring a stable C*-algebra A as B \otimes K in a canonical way. Then it is shown that this method can be p…
