Notes on computing minimal approximant bases

pdf-format:


Abstract

We show how to transform the problem of computing solutions
to a classical Hermite Pade approximation problem for an input
vector of dimension $m imes 1$, arbitrary degree constraints
$(n_1,n_2,ldots,n_m)$, and order $N := (n_1 + 1) + cdots +
(n_m + 1) - 1$, to that of computing a minimal approximant
basis for a matrix of dimension $O(m) imes O(m)$, uniform
degree constraint $Theta(N/m)$, and order $Theta(N/m)$.
