The vanishing ideal of a finite set of points with multiplicity structures
Na Lei, Xiaopeng Zheng, Yuxue Ren
Given a finite set of arbitrarily distributed points in affine space with arbitrary multiplicity structures, we present an algorithm to compute the reduced Groebner basis of the va…

Fitzpatrick Algorithm for Multivariate Rational Interpolation
Peng Xia, Shugong Zhang, Na Lei
In this paper, we first apply the Fitzpatrick algorithm to osculatory rational interpolation. Then based on Fitzpatrick algorithm, we present a Neville-like algorithm for Cauchy in…
