 报告摘要:

 In this talk, we present a priori error analysis of a hybridizable discontinuous Galerkin (HDG) method for a distributed optimal control problem governed by convection-diffusion equations. This work is the first stepping stone for devising HDG methods for more general optimal control problems. The error estimates are established based on the projection-based approach recently used to analyze the HDG method for the diffusion equation. We proved that for approximations of degree k on conforming meshes, the orders of convergence of the approximation to fluxes and scalar variables are k + 1 when the local stabilization parameter is suitably chosen.
