AB - <p style="text-align: justify;">A technique of orthogonality correction in an element is
introduced and applied to superconvergence analysis in finite element
method. Ultraconvergence results for rectangular elements of odd degree $n \geq 3$ are derived in the case of variable coefficients.</p>
