Chern Numbers of Smooth Varieties via Homotopy Continuation and Intersection Theory

Algebraic Geometry 2009-09-14 v1 Commutative Algebra

Abstract

Homotopy continuation provides a numerical tool for computing the equivalence of a smooth variety in an intersection product. Intersection theory provides a theoretical tool for relating the equivalence of a smooth variety in an intersection product to the degrees of the Chern classes of the variety. A combination of these tools leads to a numerical method for computing the degrees of Chern classes of smooth projective varieties in P^n. We illustrate the approach through several worked examples.
