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…

Abundance of entire solutions to nonlinear elliptic equations by the variational method
L. M. Lerman, P. E. Naryshkin, A. I. Nazarov
We study entire bounded solutions to the equation in . Our approach is purely variational and is based on concentration arguments and symmetry consi…
