On a theorem in spline theory
Yu. V. Kupriyanova Faculty of Mathematics, Saratov State University,
ul. Astrakhanskaya 83, Saratov, 410012, Russia
Abstract:
A Hermite spline of third degree is constructed on a three-dimensional simplex. The deviation of its directional derivatives up to the third order is estimated in angle-free terms. The resulting estimates hold for any tetrahedron irrespective of its geometry.
Key words:
Hermite spline, cubic element, tetrahedral Hermite polynomials, finite elements.
