Popis: 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.
