Categorical Landstad duality for actions
S. Kaliszewski, John Quigg
We show that the category A(G) of actions of a locally compact group G on C*-algebras (with equivariant nondegenerate *-homomorphisms into multiplier algebras) is equivalent, via a…
Hecke C*-algebras and semidirect products
S. Kaliszewski, Magnus B. Landstad, John Quigg
We analyze Hecke pairs (G,H) and the associated Hecke algebra when G is a semidirect product N x Q and H = M x R for subgroups M of N and R of Q with M normal in N. Conditions are…
Landstad's characterization for full crossed products
S. Kaliszewski, John Quigg
Full C*-crossed products by actions of locally compact groups are characterized via the existence of suitable maximal coactions, in analogy with Landstad's characterization of redu…
Bundles of C*-correspondences over directed graphs and a theorem of Ionescu
John Quigg
We give a short proof of a recent theorem of Ionescu which shows that the Cuntz-Pimsner C*-algebra of a certain correspondence associated to a Mauldin-Williams graph is isomorphic…
