Transformation Optics for the Modelling of Waves in a Universe with Nontrivial Topology

Tracey Balehowsky, Matti Lassas, Pekka Pankka +1

We consider how transformation optics and invisibility cloaking can be used to construct models in subsets $R^{3}$ with a varying metric, where the time-harmonic waves for a…

Quasiregular curves: Hölder continuity and higher integrability

Jani Onninen, Pekka Pankka

We show that a $K$ -quasiregular $ω$ -curve from a Euclidean domain to a Euclidean space with respect to a covector $ω$ is locally $(1/ K) (∥ ω ∥ /∣ ω ∣_{ℓ_{1}})$ -Hölder continu…

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…
