TropicalToric

A Macaulay2 package for toric intersection theory using tropical geometry.

Installation

Download the package, extract it. Open a terminal and cd to the extracted folder, open Macaulay2 and install the package with

installPackage "TropicalToric"

Example

First, load the package with

needsPackage "TropicalToric"

As an example, we can compute the class of a line in the projective plane

X = toricProjectiveSpace 2;
R = QQ[x,y];
I = ideal(x+y+1);
L = classFromTropical(X,I)

We can compute intersection products of a toric divisor and a toric cycle and their intersection number

C = X_0 * X_{0}
degCycle(C)
