Essential freeness, allostery and -stability of crossed products
Eusebio Gardella, Shirly Geffen, Rafaela Gesing +2
We explore classifiability of crossed products of actions of countable amenable groups on compact, metrizable spaces. It is completely understood when such crossed products are sim…

Dynamical comparison and -stability for crossed products of simple -algebras
Eusebio Gardella, Shirly Geffen, Petr Naryshkin +1
We establish -stability for crossed products of outer actions of amenable groups on -stable -algebras under a mild technical assumption which we call…

Classification of irreversible and reversible Pimsner operator algebras
Adam Dor-On, Søren Eilers, Shirly Geffen
Since their inception in the 30's by von Neumann, operator algebras have been used in shedding light in many mathematical theories. Classification results for self-adjoint and non-…
