review text: Summary: 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 \(k\) (\(k \geq 1\)), a supercloseness property of \(k + 1 / 2\) in DG norm is established on S-type mesh. Numerical experiments complement the theoretical results.
