Chevalley formulae for the motivic Chern classes of Schubert cells and for the stable envelopes

Leonardo C. Mihalcea, Hiroshi Naruse, Changjian Su

We prove a Chevalley formula to multiply the motivic Chern classes of Schubert cells in a generalized flag manifold $G/P$ by the class of any line bundle ${\mathcal{L}}_{\hat{I}}»$. Our form…
