The range of Hardy number on comb domains

  title={The range of Hardy number on comb domains},
  author={Christina Karafyllia},
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 entire plane minus an infinite number of vertical rays symmetric with respect to the real axis. In this paper we prove that for any p ∈ [1,+∞], there is a comb domain with Hardy number equal to p and this result is sharp. It is known that the Hardy number is related with the moments of the exit time…

On the Hardy number of comb domains
Let H (D) be the Hardy space of all holomorphic functions on the unit disk D with exponent p > 0. If D 6= C is a simply connected domain and f is the Riemann mapping from D onto D, then the Hardy
On the finiteness of moments of the exit time of planar Brownian motion from comb domains
A comb domain is defined to be the entire complex plain with a collection of vertical slits, symmetric over the real axis, removed. In this paper, we consider the question of determining whether the
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
Hardy spaces and unbounded quasidisks
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
Exit Times of Brownian Motion, Harmonic Majorization, and Hardy Spaces
Let R be an open, connected subset of R n \(n \geqslant 2\), X a Brownian motion in R n starting at a point x in R, and \(\tau\) the first time X leaves R: $$\tau \left( \omega \right) = \inf
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
The hyperbolic metric and geometric function theory
The goal is to present an introduction to the hyperbolic metric and various forms of the Schwarz-Pick Lemma. As a consequence we obtain a number of results in geometric function theory.
