Original Abstract

The problem of quadratic interpolation of smooth functions in two variables in nodes which are vertices of unstructured triangulations is studied. Every vertex of a triangulation from an extensive class of triangulations is shown to belong to a local six-tuple of vertices in which the problem of quadratic Lagrange interpolation is solvable uniquely with an error of optimal order.

Keywords

interpolation of functions in two variables; strongly regular classes of triangulations; poised sets of vertices
