Continuous boundary values of conformal maps

Zhijian Qiu

Let $G$ be a bounded simply connected domain in the complex plane. A point $a \in \partial G$ is said to be accessible from inside of $G$ if there is a Jordan arc $J$ such that $J\s…

Beurling's Theorem And Invariant Subspaces For The Shift On Hardy Spaces

Zhijian Qiu

Let $G$ be a bounded open subset in the complex plane and let $H^{2} (G)$ denote the Hardy space on $G$ . We call a bounded simply connected domain $W$ perfectly connected if the bou…

The Structure of the Closure of the Rational Functions in $L^{q}$ ( $μ$ )$

Zhijian Qiu

Let $K$ be a compact subset in the complex plane and let $A (K)$ be the uniform closure of the functions continuous on $K$ and analytic on $K^{\circ}$ . Let $μ$ be a positive finite…

Continuous extension of conformal maps

Zhijian Qiu

For a simply connected domain $G$ , let $\partial_{a} G$ be the set of accessible points in $\partial G$ and let $\partial_{n} G = \partial G - \partial_{a} G$ . A point $a \in \partial G$ i…

The Riemann Mapping Problem

Zhijian Qiu

In this article we investigate the century-old continuous extension problem of the Riemann map. Let $G$ be a simply connected domain. We call $λ$ in $\partial G$ a multiple point i…

Carleson measures on planar sets

Zhijian Qiu

In this paper, we investigate what are Carleson measures on open subsets in the complex plane. A circular domain is a connected open subset whose boundary consists of finitely many…
