The CotangentSchubert Macaulay2 package

Paul Zinn-Justin

Vol. 14 (2024), 73–85
Abstract

We present the Macaulay2 package CotangentSchubert. We show its use in computing motivic Chern and Segre classes of Schubert cells of partial flag varieties and in checking recently found combinatorial formulae for their products.

Keywords
Schubert calculus, motivic Chern classes
