Richardson tableaux and Schubert positivity

We compute the Schubert cycle expansion of those irreducible components of Springer fibers equal to Richardson varieties. This generalizes work of Güemes in the case of a hook shape and answers a question of Karp-Precup.

Abstract

We compute the Schubert cycle expansion of those irreducible components of Springer fibers equal to Richardson varieties. This generalizes work of Güemes in the case of a hook shape and answers a question of Karp-Precup.
