gfan

The software computes all marked reduced Gröbner bases of an ideal. Their union is a universal Gröbner basis. Gfan contains algorithms for computing this complex for general ideals and specialized algorithms for tropical curves, tropical hypersurfaces and tropical varieties of prime ideals. In addition to the above core functions the package contains many tools which are useful in the study of Gröbner bases, initial ideals and tropical geometry. Among these are an interactive traversal program for Gröbner fans and programs for graphical renderings.
