We study the maximal number $0\le h\le+\infty$ for a given plane domain $\Omega$ such that $f\in H^p$ whenever $p<h$ and $f$ is analytic in the unit disk with values in $\Omega.$ One of our main contributions is an estimate of $h$ for unbounded $K$-quasidisks. 
The Range of Hardy Numbers for Comb Domains
Let $$D\ne \mathbb {C}$$ be a simply connected domain and f be a Riemann mapping from $$\mathbb {D}$$ onto D. The Hardy number of D is the supremum of all p for which f belongs in the Hardy space
The range of Hardy number on comb domains
Let D 6= C be a simply connected domain and f be the Riemann mapping from D onto D. The Hardy number of D is the supremum of all p for which f belongs in the Hardy space H (D). A comb domain is the
Geometric characterizations for conformal mappings in weighted Bergman spaces
We prove that a conformal mapping defined on the unit disk belongs to a weighted Bergman space if and only if certain integrals involving the harmonic measure converge. With the aid of this theorem,
On the Hardy number of comb domains
Let \({H^p}\left( \mathbb{D} \right)\) be the Hardy space of all holomorphic functions on the unit disk \(\mathbb{D}\) with exponent \(p>0\). If \(D\ne \mathbb{C}\) is a simply connected domain and
On the Hardy number of a domain in terms of harmonic measure and hyperbolic distance
Let $\psi $ be a conformal map on $\mathbb{D}$ with $ \psi \left( 0 \right)=0$ and let ${F_\alpha }=\left\{ {z \in \mathbb{D}:\left| {\psi \left( z \right)} \right| = \alpha } \right\}$ for $\alpha
On a Property of Harmonic Measure on Simply Connected Domains
Abstract Let $D\subset \mathbb{C}$ be a domain with $0\in D$. For $R>0$, let $\widehat{\unicode[STIX]{x1D714}}_{D}(R)$ denote the harmonic measure of $D\cap \{|z|=R\}$ at $0$ with respect to the

On the degenerate Beltrami equation
We study the well-known Beltrami equation under the assumption that its measurable complex-valued coefficient μ(z) has the norm ∥μ∥∞ = 1. Sufficient conditions for the existence of a homeomorphic

The Hardy Class of Geometric Models and the Essential Spectral Radius of Composition Operators
Letφbe an analytic map of the disk into itself (that fixes the origin). Then, it is well known thatφinduces a bounded composition operatorCφon the Hardy spaceH2(D). Also, by a classical result of
Mean growth of Koenigs eigenfunctions
In 1884, G. Koenigs solved Schroeder's functional equation f o a = Af in the following context: ( is a given holomorphic function mapping the open unit disk U into itself and fixing a point a E U, f
The Hardy class of a spiral-like function.
A determination is made of the Hardy classes to which a spiral-like univalent function and its derivative belong. An estimate for the size of the Taylor coefficients is deduced. Let/(z) be analytic
