A Neohookean model of plates
Tadeusz Iwaniec, Jani Onninen, Pekka Pankka +1
This article is about hyperelastic deformations of plates (planar domains) which minimize a neohookean type energy. Particularly, we investigate a stored energy functional introduc…
Let the Beauty of Harmonic Analysis be Revealed Through Nonlinear PDEs; A Work of Art in Three Sketches
Tadeusz Iwaniec
Paraphrasing Luciano Pavarotti on music, let me say: "Learning mathematics by only reading about it is like making love by e-mail."
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…
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…
Diffeomorphic approximation of Sobolev homeomorphisms
Tadeusz Iwaniec, Leonid V. Kovalev, Jani Onninen
Every homeomorphism h : X -> Y between planar open sets that belongs to the Sobolev class W^{1,p}(X,Y), 1<p<\infty, can be approximated in the Sobolev norm by diffeomorphisms.
