On -algebras associated to transfer operators for countable-to-one maps
K. Bardadyn, B. K. Kwasniewski, A. V. Lebedev
Our initial data is a transfer operator for a continuous, countable-to-one map defined on an open subset of a locally compact Hausdorff space . Then may be id…
Spectrum of weighted isometries: C*-algebras, transfer operators and topological pressure
K. Bardadyn, B. Kwaśniewski
We study the spectrum of operators on a Hilbert space where is an isometry and belongs to a commutative -subalgebra such t…
Noncommutative Cartan C*-subalgebras
B. K. Kwasniewski, R. Meyer
We characterise Exel's noncommutative Cartan subalgebras in several ways using uniqueness of conditional expectations, relative commutants, or purely outer inverse semigroup action…
Stone duality and quasi-orbit spaces for generalised C*-inclusions
B. K. Kwaśniewski, R. Meyer
Let and be -algebras with . Exploiting the duality between sober spaces and spatial locales, and the adjunction between restriction and induction for…
Nica-Toeplitz algebras associated with product systems over right LCM semigroups
Bartosz K. Kwasniewski, Nadia S. Larsen
We prove uniqueness of representations of Nica-Toeplitz algebras associated to product systems of -correspondences over right LCM semigroups by applying our previous abstract…
Crossed products by endomorphisms of -algebras
B. K. Kwasniewski
In the first part of the paper, we develop a theory of crossed products of a -algebra by an arbitrary (not necessarily extendible) endomorphism . We consider rel…
