Abstract:

In this paper we analyze the finite element discretization for the first-order system least squares mixed model for the second-order elliptic problem by means of using nonconforming and conforming elements to approximate displacement and stress, respectively. Moreover, on arbitrary regular quadrilaterals, we propose new variants of both the rotated ${\mathcal Q}_1$ nonconforming element and the lowest-order Raviart-Thomas element.
