Bug#480089: RFP: gfan -- A package for computing with Groebner fans
Package: wnpp
Priority: wishlist
* Package name: gfan
* URL: http://www.math.tu-berlin.de/~jensen/software/gfan/gfan.html
* License: GPL
Programming Lang: C++
* Description: A package for computing with Groebner fans
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 Groebner 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. Among these are an
interactive traversal program for Groebner fans and programs for
graphical renderings. For ordinary Groebner basis computations Gfan
is not competitive in speed compared to programs such as CoCoA,
Singular and Macaulay2.
I have a draft packaging available in the apt repository described at
<http://wiki.sagemath.org/DebianSAGE> that I run for coordinating the
packaging of SAGE for Debian (#455292).
This package needs a man page.
Since I don't have the time to maintain all 26 source packages I've
created as part of my effort to package SAGE's dependencies for Debian,
I'm looking for someone to adopt this package and maintain it in Debian.
