Abstract

For a given arbitrary triangulation of R2, we construct an interpolating operator which is exact for the polynomials in two variables of total degree ≤2. This operator is local, in the sense that the information around an interpolation node is taken from a small region around this point. We study the remainder of the interpolation formula.
