Groebner fan of an ideal

by Marshall Hampton; (needs sage-2.11 or higher, with gfan-0.3 interface)

Numerical Solutions of Polynomial Systems with PHCpack FIXME

by Marshall Hampton; requires phcpack optional package (PHCpack written by Jan Verschelde). The example below is a two-parameter deformation of the cyclic-6 problem. Solution paths are tracked through the parameter homotopy.
