On split exact sequences and KK-equivalences of amplified graph C*-algebras

Jesse Reimann, Sophie Emma Zegers

We give a general methodology for constructing split exact sequences of amplified graph C*-algebras with sinks. This in turn allows us to construct explicit KK-equivalences with $\…

On amplified graph C*-algebras as cores of Cuntz-Krieger algebras

Francesco D'Andrea, Sophie Emma Zegers

Given a finite directed acyclic graph , we construct from it two graphs and , one by adding a loop at every vertex of and one by replacing every arrow of by c…

Equivariant isomorphism of Quantum Lens Spaces of low dimension

Søren Eilers, Sophie Emma Zegers

The quantum lens spaces form a natural and well-studied class of noncommutative spaces which can be subjected to classification using algebraic invariants by drawing on the fully d…

A quantum twistor bundle

Sophie Emma Zegers

We investigate a quantum twistor bundle constructed as a -quotient of the quantum instanton bundle of Bonechi, Ciccoli and Tarlini. It is an example of a noncommutative bundl…

On the classification and description of quantum lens spaces as graph algebras

Thomas Gotfredsen, Sophie Emma Zegers

We investigate quantum lens spaces, , introduced by Brzeziński-Szymański as graph -algebras. We give a new description of $C(L_q^{2n+1}(r;\unde…

Split extensions and KK-equivalences for quantum projective spaces

Francesca Arici, Sophie Emma Zegers

We study the noncommutative topology of the -algebras of the quantum projective spaces within the framework of Kasparov's bivariant K-theory. In particu…
