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…
Formal topology and constructive mathematics: the Gelfand and Stone-Yosida representation theorems
Thierry Coquand, Bas Spitters
We present a constructive proof of the Stone-Yosida representation theorem for Riesz spaces motivated by considerations from formal topology. This theorem is used to derive a repre…
Finite Rank Toeplitz Operators: Some Extensions of D.Luecking's Theorem
Alexey Alexandrov, Grigori Rozenblum
The recent theorem by D.Luecking about finite rank Bergman-Toeplitz operators is extended to weights being distributions with compact support and to the spaces of harmonic function…
Finite rank Bergman-Toeplitz and Bargmann-Toeplitz operators in many dimensions
Grigori Rozenblum, Nikolay Shirokov
The recent theorem by D. Luecking that finite rank Toeplitz-Bergman operators must be generated by a measure consisting of finitely many point masses is carried over to the many-di…
