Weighted Big Lipschitz algebras of analytic functions and closed ideals
We give the smallest closed ideal with given hull and inner factor for some
weighted big Lipschitz algebras of analytic functions
Closed ideals in analytic weighted Lipschitz algebras
We obtain a complete description of closed ideals in weighted Lipschitz
algebras of analytic functions on the unit disk satisfying the
following condition where is a modulus of continuity satisfying some
regularity conditions.Comment: 22 page
Closed ideals in some algebras of analytic functions
We obtain a complete description of closed ideals of the algebra
\mathcal{D}\cap \mathrm{lip}_\alpha}, where
is the Dirichlet space and \mathrm{lip}_\alpha} is the algebra
of analytic functions satisfying the Lipschitz condition of order Comment: 19 page
Idéaux fermés de certaines algèbres de fonctions analytiques.
In this thesis, we are interested to descrip the closed ideals in some algebras of analytic functions on the complex unit disk or polydisk.Dans cette thèse, nous nous intéressons à la description des idéaux fermés de certaines algèbres de fonctions analytiques sur le disque et le polydisque unité
HELSON SETS, SPECTRAL SYNTHESIS AND APPLICATIONS TO OPERATORS
In this paper we highlight the role played by Helson sets and/or sets of spectral synthesis in some recent results in operator theory. We consider in particular the results on the cyclicity in L p spaces, the Katznelson-Tzafriri type theorems and polynomially bounded operators
On closed ideals in the big Lipschitz algebras of analytic functions
In this paper we study the closed ideals in the big Lipschitz algebras of analytic functions on the unit disk. More precisely we give the smallest closed ideal with given hull and inner factor.
Idéaux fermés d'algèbres de Beurling analytiques sur le bidisque
International audienceWe study the closed ideal in the Beurling algebras \aA^{+}_{\alpha,\beta} of holomorphic function in the bidisc such that We characterize the functions f\in \aA^+_{\alpha,\beta}, under a restriction on their zero sets, such that the closed ideal generated by coincides with the ideal of all functions vanishing on the zero set of
