In this web page we introduce several Maple 7 programs dedicated to the problems of counting integer flows on networks. A paper explaining these techniques is also available here. The techniques that are being used rely on the notion of total residue on the space of rational functions with denominator supported on a hyperplane arrangement. The methods extend to the general problem of counting lattice points inside unimodular convex polytopes.

Via this web page we release our software and provide related links. If you have any comments or questions please send an email to totalresidue@math.ucdavis.edu.
