SUMMARY:Seminar in Numerical Analysis: Ira Neitzel (Universität Bonn)
DESCRIPTION:joint work with Dominik Hafemeyer\, Florian Mannel and Boris Ve
 xler\\r\\n We consider a convex  optimal control problem governed by a par
 tial differential equation in  one space dimension which is controlled by 
 a right-hand-side living in  the space of functions with bounded variation
 . These functions tend to favor optimal controls that are piecewise  const
 ant with often finitely many jump poins. We are interested in  deriving fi
 nite element discretization error estimates for the controls  when the sta
 te ist discretized with usual piecewise linear finite elements\, and the c
 ontrols is either variationally  discrete or piecwise constant. Due to the
  structure of the objective  function\, usual techniques for estimating th
 e control error cannot be  applied. Instead\, these have to be derived fro
 m (suboptimal) error estimates for the state\, which can later be improved
 . \\r\\nFor further information about the seminar\, please visit this web
 page [t3://page?uid=current].
