Un schéma d'interpolation rationnel sur un quadrilatère de classe
No full textLet be a partition of a polygonal domain of the plan
into convexe quadrilaterals. Given a regular function f , we construct a
function πƒ
∈ C2(Ω), interpolating position values and
derivatives of f up of order 2 at vertices of On each
quadrilateral
πƒ|Q is a finite element obtained
from a polynomial scheme of FVS type by adding some rational functions
