Lipschitz regularity for inner-variational equations
Tadeusz Iwaniec, Leonid V. Kovalev, Jani Onninen
We obtain Lipschitz regularity results for a fairly general class of nonlinear first-order PDEs. These equations arise from the inner variation of certain energy integrals. Even in…
Approximation up to the boundary of homeomorphisms of finite Dirichlet energy
Tadeusz Iwaniec, Leonid V. Kovalev, Jani Onninen
Let X and Y be planar Jordan domains of the same finite connectivity, Y being inner chordarc regular (such are Lipschitz domains). Every homeomorphism h:X->Y in the Sobolev space $…
n-Harmonic mappings between annuli
Tadeusz Iwaniec, Jani Onninen
The central theme of this paper is the variational analysis of homeomorphisms $h\colon \mathbb X \onto \mathbb Y$ between two given domains $\mathbb X, \mathbb Y \subset \mathbb R^…
An Essay on the Interpolation Theorem of Józef Marcinkiewicz - Polish Patriot
Tadeusz Iwaniec
In memory of Polish mathematicians murdured by the Soviets and the Nazis. The total record of accomplishments of Marcinkiewicz in his short life, his talent, perceptions rich in co…
