Spectrally reasonable measures II
Przemysław Ohrysko, Michał Wojciechowski
A measure on a locally compact Abelian group is said to have a natural spectrum if its spectrum is equal to the closure of the range of the Fourier-Stieltjes transform. In this pap…

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…

Inversion problem in measure and Fourier-Stieltjes algebras
Przemysław Ohrysko, Mateusz Wasilewski
In this paper we study the inversion problem in measure and Fourier-Stieltjes algebras from qualitative and quantitative point of view extending the results obtained by N. Nikolski…
