Fully discrete best approximation type estimates in for finite element discretizations of the transient Stokes equations
Niklas Behringer, Dmitriy Leykekhman, Boris Vexler
In this article we obtain an optimal best approximation type result for fully discrete approximations of the transient Stokes problem. For the time discretization we use the discon…

Finite Element Error Estimates for Optimal Control Problems with Pointwise Tracking
Niklas Behringer, Dominik Meidner, Boris Vexler
We consider a linear-quadratic elliptic optimal control problem with point evaluations of the state variable in the cost functional. The state variable is discretized by conforming…
