Robust Localization of the Best Error with Finite Elements in the Reaction-Diffusion Norm
Francesca Tantardini, Andreas Veeser, R"udiger Verf"urth
We consider the approximation in the reaction-diffusion norm with continuous finite elements and prove that the best error is equivalent to a sum of the local best errors on pairs…

Approximating gradients with continuous piecewise polynomial functions
Andreas Veeser
Motivated by conforming finite element methods for elliptic problems of second order, we analyze the approximation of the gradient of a target function by continuous piecewise poly…
