we present a first supercloseness analysis for higher order FEM/LDG coupled method for solving singularly perturbed convection-diffusion problem. Based on piecewise polynomial approximations of degree , a supercloseness property of in DG norm is established on S-type mesh. Numerical experiments complement the theoretical results.
