Computing Tropical Varieties in Macaulay2
The Macaulay2 package Tropical.m2 and its additional Macaulay2 files
are available here.
This
package allows some tropical computations to be done in Macaulay2.
The authors are: Carlos Améndola, Kathlén Kohn, Sara
Lamboglia, Diane Maclagan, Ben Smith, Jeff Sommars, Paolo Tripoli, and
Magdalena Zajaczkowska.
The package requires Macaulay2, which is available for
free download here.
Some methods require the latest version of gfan, which is available for free download
here.
Optional software for some of our methods is polymake (at least version 3.0), which is available for free download
here.
All of these files except Polymake will shortly be available with the
general release of Macaulay2.
Instructions for use:
- Save the zip file in a directory from which you can
start Macaulay2 and unzip it.
- Start Macaulay2 (type M2 at a terminal window, or bring up inside emacs).
- At the M2 prompt (or inside emacs), type installPackage "Polyhedra",
and hit return or F11 (depending on whether you use a terminal window or emacs).
- At the M2 prompt (or inside emacs), type installPackage "gfanInterface2",
and hit return or F11 (depending on whether you use a terminal window or emacs).
- At the M2 prompt (or inside emacs), type installPackage "Tropical",
and hit return or F11 (depending on whether you use a terminal window or emacs).
- Type viewHelp Tropical and return/F11. This will bring up a browser
window with the documentation.
- The accompanying paper "Computing tropical varieties in
Macaulay2", available as arXiv:1710.10651, describes the usage of this
package, including many examples.
