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…

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…
