A posteriori error estimates of characteristic mixed finite elements for convection-diffusion control problems
In this article, we consider fully discrete characteristic mixed finite elements for convection-diffusion optimal control problems. We use the characteristic line method to treat the hyperbolic part of the state equation as a directional derivative. The state and the co-state are discretized by the...
