Sharp angle estimates for second order divergence operators
Hannes Meinlschmidt, Joachim Rehberg
This article is about the (minimal) sector containing the numerical range of the principal part of a linear second-order elliptic differential operator defined by a form on closed…

Optimal control of quasilinear parabolic PDEs with gradient terms and pointwise constraints on the gradient of the state
Lucas Bonifacius, Fabian Hoppe, Hannes Meinlschmidt +1
We derive existence results and first order necessary optimality conditions for optimal control problems governed by quasilinear parabolic PDEs with a class of first order nonlinea…
