On the numerical range of second order elliptic operators with mixed boundary conditions in
Ralph Chill, Hannes Meinlschmidt, Joachim Rehberg
We consider second order elliptic operators with real, nonsymmetric coefficient functions which are subject to mixed boundary conditions. The aim of this paper is to provide unifor…

Extrapolated Elliptic Regularity and Application to the van Roosbroeck system of Semiconductors
Hannes Meinlschmidt, Joachim Rehberg
In this paper we present a general extrapolated elliptic regularity result for second order differential operators in divergence form on fractional Sobolev-type spaces of negative…
