WebMotivated by the recent discovery of a simple quantization procedure for Schubert polynomials we study the expansion of Schur and Schubert polynomials into standard elementary monomials (SEM). The SEM expansion of Schur polynomials can be described algebraically by a simple variant of the Jacobi–Trudi formula and combinatorially by a … WebA Bruhat interval is a diagram that represents all the different ways you could reverse the order of a collection of objects by only swapping two of them at a time. The KL polynomials tell mathematicians something deep …
