Singularities In L p-quasidisks
Tadeusz Iwaniec, Jani Onninen, Zheng Zhu
We study planar domains with exemplary boundary singularities of the form of cusps. A natural question is how much elastic energy is needed to flatten these cusps; that is, to remo…

Deformations of Bi-conformal Energy and a new Characterization of Quasiconformality
Tadeusz Iwaniec, Jani Onninen, Zheng Zhu
The concept of hyperelastic deformations of bi-conformal energy is developed as an extension of quasiconformality. These are homeomorphisms between domains $ X, Y \subs…
