Expected term bases for generic multivariate Hermite interpolation

摘要

The main goal of the paper is to find an effective estimation for the minimal number of points in ${mathbb{K}}^{2}$ in general position for which the basis for Hermite interpolation consists of the first ? terms (with respect to total degree ordering). As a result we prove that the space of plane curves of degree at most d having singularities of multiplicity ≤ m in general position has the expected dimension if the number of low order singularities (of multiplicity k ≤ 12) is greater then some r(m, k). Additionally, the upper bounds for r(m, k) are given.
