Abstract: | Summary A general construction of rational finite elements of serendip type on convex quadrilaterals is described in this paper. A first technique consists in eliminating formerly introduced nodes; a second possibility is to use the transformation of Coxeter-Wachspress. Error bounds are given for the associate interpolation. |
