Abstract
In the present paper, we examine a Crouzeix-Raviart approximation for non-linear partial differential equations having a -structure for some and . We establish a priori error estimates, which are optimal for all and , medius error estimates, i.e., best-approximation results, and a primal-dual a posteriori error estimate, which is both reliable and efficient. The theoretical findings are supported by numerical experiments.
