We introduce certain$C^*$-algebras andk-graphs associated tokfinite-dimensional unitary representations$\rho _1,\ldots ,\rho _k$of a compact groupG. We define a higher rank Doplicher-Roberts algebra$\mathcal {O}_{\rho _1,\ldots ,\rho _k}$, constructe

We introduce the $C^*$-algebra $C^*(\kappa)$ generated by the Koopman representation $\kappa$ of an \'etale groupoid $G$ acting on a measure space $(X,\mu)$. We prove that for a level transitive self-similar action $(G,E)$ with $E$ finite and $|uE^1|

Introduction: Focal epilepsy (possible with secondary generalization) may be a secondary complication to any brain damage (traumatic, vascular, infectious), and is characterized by abnormal excessive neuronal activity with motor, cognitive and psycho

We consider C ⁎ -algebras constructed from compact group actions on complex vector bundles E → X endowed with a Hermitian metric. An action of G by isometries on E → X induces an action on the C ⁎ -correspondence Γ ( E ) over C ( X ) consist

A Bridge to Higher Mathematics is more than simply another book to aid the transition to advanced mathematics. The authors intend to assist students in developing a deeper understanding of mathematics and mathematical thought. The only way to underst

In this note we analyze the C ∗ C^{\ast } -algebra associated with a branched covering both as a groupoid C ∗ C^{\ast } -algebra and as a Cuntz-Pimsner algebra. We determine conditions when the algebra is simple and purely infinite. We indicate h

We present the continuous graph approach for some generalizations of the CuntzKrieger algebras. These algebras are simple, nuclear, and purely infinite, with rich Ktheory. They are tied with the dynamics of a shift on an infinite path space. Interest
