Algebraic structures, such as groups, rings and fields, provide a rigorous language for expressing symmetry and invariance in numerous mathematical contexts. Their integration with the theory of ...

Let $(A, G, \tau)$ be a noncommutative dynamical system, i.e. $A$ is a $C^\ast$-algebra, $G$ a topological group and $\tau$ an action of $G$ on $A$ by $^\ast ...

Iteration of a rational function R gives a complex dynamical system on the Riemann sphere. We introduce a C*-algebra 𝓞R associated with R as a Cuntz-Pimsner algebra of a Hilbert bimodule over the ...
