Feb 6 at 0:50 | comment | added | Zach H | You can derive the Stanley symmetric function result from Monk's rule, but I'm not aware of a purely geometric exposition. The toric Schur example is from 'Positroid varieties: juggling and geometry' by Knutson, Lam, and Speyer. The $k$-Schur example comes from work of Thomas Lam on affine Stanley symmetric functions. Another example is June Huh's proof for positivity of Chern-Schwartz-MacPherson classes. | |
