Gfan is a software package for computing Groebner fans and tropical
|
||
|
|
varieties. These are polyhedral fans associated to polynomial ideals.
|
||
|
|
The maximal cones of a Groebner fan are in bijection with the marked
|
||
|
|
reduced Groebner bases of its defining ideal. The software computes
|
||
|
|
all marked reduced Groebner bases of an ideal. Their union is a
|
||
|
|
universal Greobner basis. The tropical variety of a polynomial ideal
|
||
|
|
is a certain subcomplex of the Groebner fan. 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
|
||
|
|
Groebner bases, initial ideals and tropical geometry.

This port provides gfan together with some handy symlinks. The static
|
||
|
|
library libgfan.a is provided by the port math/gfanlib.
