C*-irreducible regular inclusions, Galois correspondence and aperiodicity
B. K. Kwaśniewski, R. Meyer
We characterise C*-irreducible regular C*-inclusions using a number of different conditions considered by different authors. In particular, we show that all C*-irreducible regular…
Ideal structure and pure infiniteness of inverse semigroup crossed products
B. K. Kwaśniewski, R. Meyer
Let be a -inclusion. We give efficient conditions under which separates ideals in , and is purely infinite if every positive element in is proper…
Essential crossed products for inverse semigroup actions: simplicity and pure infiniteness
B. K. Kwasniewski, R. Meyer
We study simplicity and pure infiniteness criteria for C*-algebras associated to inverse semigroup actions by Hilbert bimodules and to Fell bundles over etale not necessarily Hausd…
Topological freeness for -correspondences
T. M. Carlsen, B. K. Kwasniewski, E. Ortega
We study conditions that ensure uniqueness theorems of Cuntz-Krieger type for relative Cuntz-Pimsner algebras associated to a -correspondence over a $C^…
Pure infiniteness and ideal structure of -algebras associated to Fell bundles
B. K. Kwaśniewski, W. Szymański
We investigate structural properties of the reduced cross-sectional algebra of a Fell bundle over a discrete group . Conditions allowing one t…
Ideal structure of crossed products by endomorphisms via reversible extensions of -dynamical systems
B. K. Kwasniewski
We consider an extendible endomorphism of a -algebra . We associate to it a canonical -dynamical system that extends and is `reversible' in the sen…
Topological aperiodicity for product systems over semigroups of Ore type
B. K. Kwasniewski, W. Szymanski
We prove a version of uniqueness theorem for Cuntz-Pimsner algebras of discrete product systems over semigroups of Ore type. To this end, we introduce Doplicher-Roberts picture of…
