- 49J20 Optimal control problems involving partial differential equations
Abstract :
The discretization of control functions by piecewise constant and
piecewise linear functions is considered for linear-quadratic
elliptic optimal control problems. Error estimates are derived for
the optimal controls. Special emphasis is laid on the case of
boundary control and convex polygonal domains.
