Traces of Sobolev functions and higher integrability
Robert Denk, Franz Gmeineder, Paul Stephan
We give a sharp characterization of how additional integrability in the interior improves the integrability of boundary traces of -Sobolev functions. The optimali…

Stability analysis for a plate-membrane system without geometric condition
Bienvenido Barraza Martínez, Robert Denk, Jonathan González Ospino +1
In this work, we consider a transmission problem describing a thermoelastic plate surrounding a membrane without any mechanical damping. The main results consist of the lack of exp…

On the Singular Limit in Hibler's Sea Ice Model
Robert Denk, Franz Gmeineder, Matthias Hieber
We establish the existence of energy-driven solutions to the momentum balance equation in Hibler's sea ice model. As a main novelty and different from previous results, we deal wit…
