Summary For second order linear elliptic problems, it is proved that theP 1-nonconforming finite element method has the sameL ∞-asymptotic accuracy as theP 1-conforming one. This result is applied to derive optimalL ∞-error estimates for both the displacement and the stress fields of the lowest order Raviart-Thomas mixed finite element method, and a superconvergence result at the barycenter of each element.
