How to generate all possible rational Wilf-Zeilberger pairs?
A Wilf--Zeilberger pair in the discrete case satisfies the equation
. We present a structural
description of all possible rational Wilf--Zeilberger pairs and their
continuous and mixed analogues.Comment: 17 pages, add the notion of pseudo residues in the differential case,
and some related papers in the reference, ACMES special volume in the Fields
