Degeneracy Loci and Schubert Polynomials

Anna Weigandt (UIUC Math)

Abstract: Given a morphism of vector bundles over a variety, we wish to understand the locus of points for which the induced map on the fibers has at most rank $r$. Under suitable conditions, this degeneracy locus is a subvariety which represents a class in the cohomology of the base. We will discuss specific examples of such degeneracy loci and describe certain polynomials which appear in this analysis.
