In this section, we shall revisit the Broken Sobolev spaces and modify those terms involving U by Lesaint-Raviart upwind technique and then apply the discontinuous Galerkin method to discrete those space-derivative terms in (1)-(4) to design an upwind nonsymmetric interior penalty Galerkin (NIPG) method.
Quite popular is the NIPG (nonsymmetric interior penalty Galerkin) method, which was first introduced in [28].
Taking [THETA] = 1, 0 and -1, we obtain the symmetric (SIPG), incomplete (IIPG) and nonsymmetric (NIPG) variants of the approximation of the diffusion terms.
Let assumptions (H1)-(H3) and (A1)-(A2) be satisfied and let the constant [C.sub.W] satisfy the assumption from Lemmas 3.7, 3.8 and 3.9 corresponding to the NIPG, SIPG and IIPG version, respectively.
