Spectrum of weighted isometries: C*-algebras, transfer operators and topological pressure

K. Bardadyn, B. Kwaśniewski

We study the spectrum of operators $a T \in B (H)$ on a Hilbert space $H$ where $T$ is an isometry and $a$ belongs to a commutative $C^{*}$ -subalgebra $C (X) ≅ A \subseteq B (H)$ 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…
