A note on spectral triples and quasidiagonality
Adam Skalski, Joachim Zacharias
Spectral triples (of compact type) are constructed on arbitrary separable quasidiagonal C*-algebras. On the other hand an example of a spectral triple on a non-quasidiagonal algebr…

Approximation properties and entropy estimates for crossed products by actions of amenable discrete quantum groups
Adam Skalski, Joachim Zacharias
We construct explicit approximating nets for crossed products of C*-algebras by actions of discrete quantum groups. This implies that C*-algebraic approximation properties such as…

Noncommutative topological entropy of endomorphisms of Cuntz algebras
Adam Skalski, Joachim Zacharias
Noncommutative topological entropy estimates are obtained for polynomial gauge invariant endomorphisms of Cuntz algebras, generalising known results for the canonical shift endomor…
