 Morley–Wang–Xu element

In applied mathematics, the Morlely–Wang–Xu (MWX) element is a canonical construction of a family of piecewise polynomials with the minimal degree elements for any formula_1-th order of elliptic and parabolic equations in any spatial-dimension formula_2 for formula_3.The MWX element provides a consistent approximation of Sobolev space formula_4 in formula_2.
