abstract = {<p style="text-align: justify;">In this paper we use the Generalized Multiscale Finite Element Method
(GMsFEM) framework, introduced in [26], in order to solve nonlinear elliptic equations with high-contrast coefficients. The proposed solution method involves linearizing the equation so that coarse-grid quantities of previous solution iterates can be regarded as auxiliary parameters within the problem formulation. With this convention,
we systematically construct respective coarse solution spaces that lend themselves
to either continuous Galerkin (CG) or discontinuous Galerkin (DG) global formulations. Here, we use Symmetric Interior Penalty Discontinuous Galerkin approach.
Both methods yield a predictable error decline that depends on the respective coarse
space dimension, and we illustrate the effectiveness of the CG and DG formulations
by offering a variety of numerical examples.</p>},
