Cyclicity in Besov-Dirichlet spaces from the Corona Theorem
Yabreb Mohamed Egueh, Karim Kellay, Mohamed Zarrabi
Tolokonnikov's Corona Theorem is used to obtain two results on cyclicity in Besov-Dirichlet spaces.
Explicit bounds for separation between Oseledets subspaces
Anthony Quas, Philippe Thieullen, Mohamed Zarrabi
We consider a two-sided sequence of bounded operators in a Banach space which are not necessarily injective and satisfy two properties (SVG) and (FI). The singular value gap (SVG)…
On powers of operators with spectrum in cantor sets and spectral synthesis
Mohamed Zarrabi
For , let be the perfect symmetric set associated with , that is $$E_ξ = \Big\{ \exp \Big( 2i π(1-ξ) \sum_{n = 1}^{+\infty} ε_{n} ξ^{n-1}…
A Szegö type theorem for truncated Toeplitz operators
Elizabeth Strouse, Dan Timotin, Mohamed Zarrabi
Truncated Toeplitz operators are compressions of multiplication operators on to model spaces (that is, subspaces of which are invariant with respect to the backward shi…
Weighted Big Lipschitz algebras of analytic functions and closed ideals
Brahim Bouya, Mohamed Zarrabi
We give the smallest closed ideal with given hull and inner factor for some weighted big Lipschitz algebras of analytic functions.
Unitary equivalence to truncated Toeplitz operators
Elizabeth Strouse, Dan Timotin, Mohamed Zarrabi
In this paper we investigate operators unitarily equivalent to truncated Toeplitz operators. We show that this class contains certain sums of tensor products of truncated Toeplitz…
