Approaching the UCT problem via crossed products of the Razak-Jacelon algebra
Selçuk Barlak, Gábor Szabó
We show that the UCT problem for separable, nuclear -algebras relies only on whether the UCT holds for crossed products of certain finite cyclic group actions on the R…

On diagonal quasi-free automorphisms of simple Cuntz-Krieger algebras
Selçuk Barlak, Gábor Szabó
We show that an outer action of a finite abelian group on a simple Cuntz-Krieger algebra is strongly approximately inner in the sense of Izumi if the action is given by diagonal qu…
