Fast, deterministic computation of the Hermite normal form and determinant of a polynomial matrix
George Labahn, Vincent Neiger, Wei Zhou
Given a nonsingular matrix of univariate polynomials over a field , we give fast and deterministic algorithms to compute its determinant and its Hermite no…
On rational functions without Froissart doublets
Bernhard Beckermann, George Labahn, Ana C. Matos
In this paper we consider the problem of working with rational functions in a numeric environment. A particular problem when modeling with such functions is the existence of Froiss…
A fast, deterministic algorithm for computing a Hermite Normal Form of a polynomial matrix
George Labahn, Wei Zhou
Given a square, nonsingular matrix of univariate polynomials over a field , we give a fast, deterministic algorithm for find…
Existence Problem of Telescopers: Beyond the Bivariate Case
Shaoshi Chen, Qing-Hu Hou, George Labahn +1
In this paper, we solve the existence problem of telescopers for rational functions in three discrete variables. We reduce the problem to that of deciding the summability of bivari…
