The spectral radius formula for Fourier-Stieltjes algebras
Przemysław Ohrysko, Maria Roginskaya
In this short note we first extend the validity of the spectral radius formula obtained in \cite{ag} to Fourier--Stieltjes algebras. The second part is devoted to showing that for…
Bounded Approximation Property for Sobolev spaces on simply-connected planar domains
Maria Roginskaya, Michal Wojciechowski
We show that Sobolev space of any planar one-connected domain has the Bounded Approximation property. The result holds independently from the properties of the bound…
A general approach to Read's type constructions of operators without non-trivial invariant closed subspaces
Sophie Grivaux, Maria Roginskaya
We present a general method for constructing operators without non-trivial invariant closed subsets on a large class of non-reflexive Banach spaces. In particular, our approach uni…
On Read's type operators on Hilbert spaces
Sophie Grivaux, Maria Roginskaya
Using Read's construction of operators without non-trivial invariant subspaces/subsets on or , we construct examples of operators on a Hilbert space whose set of…
An example of a minimal action of the free semi-group $\F^{+}_{2}$ on the Hilbert space
Sophie Grivaux, Maria Roginskaya
The Invariant Subset Problem on the Hilbert space is to know whether there exists a bounded linear operator on a separable infinite-dimensional Hilbert space such that the…
Some new examples of recurrence and non-recurrence sets for products of rotations on the unit circle
Sophie Grivaux, Maria Roginskaya
We study recurrence and non-recurrence sets for dynamical systems on compact spaces, in particular for products of rotations on the unit circle T. A set of integers is called r-Boh…
