Chern class formulas for Schubert loci

Dave Anderson

We define degeneracy loci for vector bundles with structure group , and give formulas for their cohomology (or Chow) classes in terms of the Chern classes of the bundles invol…

Positivity in the cohomology of flag bundles (after Graham)

Dave Anderson

We give a short, geometric proof of Graham's theorem on positivity in the equivariant cohomology of a flag variety, based on a transversality argument.

Schubert polynomials and classes of Hessenberg varieties

Dave Anderson, Julianna Tymoczko

Regular semisimple Hessenberg varieties are a family of subvarieties of the flag variety that arise in number theory, numerical analysis, representation theory, algebraic geometry,…
