Abstract
We will describe the Macaulay 2 package Schubert 2, written with Michael Stillman, and the mathematics behind it. It incorporates the approach of Katz and Strømme for computing Chern classes intersection numbers of interest in algebraic geometry and in physics, together with algorithmic improvements afforded by using Macaulay 2 rather than Maple as the base system.
