In this paper, both symmetric and nonsymmetric interior penalty discontinuous $hp$-Galerkin methods are applied to a class of quasi-linear elliptic problems which are of nonmonotone type. Using Brouwer’s fixed point theorem, it is shown that the discrete problem has a solution, and then, using Lipschitz continuity of the discrete solution map, uniqueness is also proved. A priori error estimates in the broken $H^1$-norm, which are optimal in $h$ and suboptimal in $p$, are derived. Moreover, on a regular mesh an $hp$-error estimate for the $L^2$-norm is also established. Finally, numerical experiments illustrating the theoretical results are provided. |
