A Family of Denominator Bounds for First Order Linear Recurrence Systems
Mark van Hoeij, Moulay Barkatou, Johannes Middeke
For linear recurrence systems, the problem of finding rational solutions is reduced to the problem of computing polynomial solutions by computing a content bound or a denominator b…

Denominator Bounds and Polynomial Solutions for Systems of q-Recurrences over K(t) for Constant K
Johannes Middeke
We consider systems A_\ell(t) y(q^\ell t) + ... + A_0(t) y(t) = b(t) of higher order q-recurrence equations with rational coefficients. We extend a method for finding a bound on th…

Matrix factoring by fraction-free reduction
Johannes Middeke, David J. Jeffrey
We consider exact matrix decomposition by Gauss-Bareiss reduction. We investigate two aspects of the process: common row and column factors and the influence of pivoting strategies…
