Sobolev homeomorphic extensions

Aleksis Koski, Jani Onninen

Let $X$ and $Y$ be $ℓ$ -connected Jordan domains, $ℓ \in N$ , with rectifiable boundaries in the complex plane. We prove that any boundary homeomorphism…

The Radó-Kneser-Choquet theorem for $p$ -harmonic mappings between Riemannian surfaces

Tomasz Adamowicz, Jarmo Jääskeläinen, Aleksis Koski

In the planar setting the Radó-Kneser-Choquet theorem states that a harmonic map from the unit disk onto a Jordan domain bounded by a convex curve is a diffeomorphism provided that…
