Abstract
The main aim of this paper is to study the nonconforming \(EQ_1^{rot}\) quadrilateral finite element approximation to second order elliptic problems on anisotropic meshes. The optimal order error estimates in broken energy norm and \(L^2\)-norm are obtained, and three numerical experiments are carried out to confirm the theoretical results.
