Extendability of functions with partially vanishing trace

Sebastian Bechtel, Russell M. Brown, Robert Haller-Dintelmann +1

Let $Ω \subseteq R^{d}$ be open and $D \subseteq \partial Ω$ be a closed part of its boundary. Under very mild assumptions on $Ω$ , we construct a bounded Sobolev extension oper…

The square root problem for second order, divergence form operators with mixed boundary conditions on $L^{p}$

Pascal Auscher, Nadine Badr, Robert Haller-Dintelmann +1

We show that, under general conditions, the operator $(- \nabla \cdot μ \nabla + 1)^{1/2}$ with mixed boundary conditions provides a topological isomorphism between $W^{1,p…
