Let A denote the Banach algebra of functions analytic in the open unit disc D and continuous in . If f and its first m derivatives belong to A, then the boundary function f(eiθ) belongs to Cm(∂D). The space Am of all such functions is a Banach algebra with the topology induced by Cm(∂D). If all the derivatives of/ belong to A, then the boundary function belongs to C∞(∂D), and the space A∞ all such functions is a topological algebra with the topology induced by C∞(∂D). In this paper we determine… 
Boundary interpolation sets for holomorphic functions smooth to the boundary and BMO
Let Ap denote the class of holomorphic functions on the unit disc whose first ^-derivatives belong to the disc algebra. We characterize the boundary interpolation sets for Ap, that is, those closed
Ideals in big Lipschitz algebras of analytic functions
For 0 < γ ≤ 1, let Λγ be the big Lipschitz algebra of functions analytic on the open unit disc D which satisfy a Lipschitz condition of order γ on D. For a closed set E on the unit circle T and an
Validity of Closed Ideals in Algebras of Series of Square Analytic Functions
We show the validity of a complete description of closed ideals of the algebra which is a commutative Banach algebra , that endowed with a pointwise operations act on Dirichlet space of algebra of
Estimates for inverses of ^{} in some quotient algebras of ⁺
We give estimates for the norm of eint in A+/I, where I is a closed ideal of A+ without inner factor, provided that the hull of I satisfies suitable geometric conditions. INTRODUCTION Let E be a
Closed ideals of A ∞ and a famous problem of Grothendieck
Using Fréchet algebraic technique, we show the existence of a nuclear Fréchet space without basis, thus providing yet another proof (of a different flavor) of a negative answer to a well known
Local Description of Closed Ideals and Submodules of Analytic Functions of One Variable. Ii
Let be a topological module (over the ring of polynomials) of vector-valued functions , holomorphic in a domain .A closed submodule is local (that is, uniquely determined by the collection , , of its
On quotients of holomorphic functions in the disc with boundary regularity conditions.
In this paper we give characterizations of those holomorphic functions in the unit disc in the complex plane that can be written as a quotient of functions in A(D), A8(D) or ?1(D) with a nonvanishing
Boundary values of absolutely convergent Taylor series
If E is a closed set of measure zero on the unit circle T = {z: I z = then a theorem of Rudin [9] asserts that every continuous function on E can be interpolated by a function which is analytic in
Boundary zero sets of $A^\infty$ functions satisfying growth conditions
Let A denote the algebra of functions analytic in the open unit disc D and continuous in D, and let AO = {fe A:ffin)e A,n=O,1,2,***}. Forf e A denote the set of zeros of f in D by ZO(f), and for f E
