KK-theoretic duality for proper twisted actions
Siegfried Echterhoff, Heath Emerson, Hyun Jeong Kim
Let the discrete group G act properly and isometrically on the Riemannian manifold X. Let C_0(X, δ) be the section algebra of a smooth locally trivial G-equivariant bundle of eleme…
The structure of crossed products of irrational rotation algebras by finite subgroups of SL_2 (Z)
Siegfried Echterhoff, Wolfgang Lueck, N. Christopher Phillips +1
Let F be a finite subgroup of SL_2 (Z) (necessarily isomorphic to one of Z/2Z, Z/3Z, Z/4Z, or Z/6Z), and let F act on the irrational rotational algebra A_θ via the restriction of t…
Inducing Primitive Ideals
Siegfried Echterhoff, Dana P. Williams
We study conditions on a -dynamical system under which induction of primitive ideals (resp. irreducible representations) from stabilizers for the action of on th…
