DEFINITIONS. 1. A~ (p > 0) is the Banach space of analytic functions f(z) in U = {z G C| \z\ < 1} that satisfy \f(z)\ = o[(l \z\)~] (\z\ > 1) with the norm \\f\\ = max{ |f(z)\(l z)} (z G If). Note that fn —• ƒ in A * and #„ —># m A~~' impl ies /^ —>,/& in A~\ 2. B (p> 0) is the Bergman space, i.e., the "analytic" subspace of L(rdrd6) in U. 3. A -00 = U A~ = U B (p > 0). A~°° is a linear topological space [1]. 4. Pis the set of all algebraic polynomials P(z). Pis dense in any of the spaces A _ p…
Cyclic vectors in the Dirichlet space
• Mathematics
• 1984
We study the Hilbert space of analytic functions with finite Dinchlet integral in the open unit disc. We try to identify the functions whose polynomial multiples are dense in this space. Theorems 1
Coefficient estimates on weighted Bergman spaces
Let A denote normalized area measure for the unit disk D in C. The Bergman space La is the sub-space of the Hilbert space L (A) consisting of functions that are also analytic in D. The monomials z

Let $\mathscr J$ be the set of inner functions whose derivatives lie in Nevanlinna class. In this note, we show that the natural map $F \to \text{Inn}(F'): \mathscr J/\text{Aut}(\mathbb{D}) \to Pseudocontinuations and the Backward Shift • Mathematics • 1998 Beurling's theorem characterizes the forward shift invariant subspaces in the Hardy space$H^2$on the open unit disk$\bold D\$. The description is in terms of an inner function, that is, a function
Cyclic Nevanlinna class functions in Bergman spaces
Let f be a function which is in both the Bergman space AP (p > 1) and the Nevanlinna class N. We show that if f is expressed as the quotient of H?? functions, then the inner part of its denominator
A ug 2 02 1 Inner functions , invariant subspaces and cyclicity in P t ( μ )-spaces
• Mathematics
• 2021
We study the invariant subspaces generated by inner functions for a class of Pt(μ)-spaces which can be identified as spaces of analytic functions in the unit disk D, where μ is a measure supported in
Cyclic Vectors in Banach Spaces of Analytic Functions
In these three lectures we consider Banach spaces of analytic functions on plane domains. If the space admits the operator of multiplication by z, then it is of interest to describe the cyclic
Invariant measures on the circle and functional equations
It is well known that real measures on the circle are characterized by their Herglotz transform, an analytic function in the unit disc. Invariance of the measure under N-multiplication translates
An abstract approach to approximations in spaces of pseudocontinuable functions
• Mathematics
• 2021
We give an abstract approach to approximations with a wide range of regularity classes X in spaces of pseudocontinuable functions K p θ, where θ is an inner function and p > 0. More precisely, we
Fonctions intérieures et vecteurs bicycliques
Abstract. We consider weights $$\omega$$ on $$\Bbb Z$$ such that $$\omega(n)\to 0$$ as $$n\to +\infty$$, $$\omega(n)\to +\infty$$ as $${n\to -\infty}$$, and satisfying some regularity
