Expansion properties of metric spaces not admitting a coarse embedding into a Hilbert space
M. I. Ostrovskii
The main purpose of the paper is to find some expansion properties of locally finite metric spaces which do not embed coarsely into a Hilbert space. The obtained result is used to…

Unitarizable representations and fixed points of groups of biholomorphic transformations of operator balls
M. I. Ostrovskii, V. S. Shulman, L. Turowska
We show that the open unit ball of the space of operators from a finite dimensional Hilbert space into a separable Hilbert space (we call it "operator ball") has a restricted form…
