abstract = {<p style="text-align: justify;">A discontinuous Galerkin finite element method for optimal control
problems having states constrained by linear parabolic PDE&#39;s is examined. The
spacial operator may depend on time and need not be self-adjoint. The schemes
considered here are discontinuous in time but conforming in space. 
Fully-discrete error estimates of arbitrary order are presented and various constants
are tracked. In particular, the estimates are valid for small values of $\alpha$, $\gamma$, where $\alpha$ denotes the penalty parameter of the cost functional and $\gamma$&nbsp; the coercivity
constant. Finally, error estimates for the convection dominated 
convection-diffusion equation are presented, based on a Lagrangian moving mesh approach.</p>},
