Weak Bruhat interval modules of the 0-Hecke algebras for stable Grothendieck polynomials

Young-Hun Kim

For a partition $\lambda$, let $G_{\lambda }^{(\beta )}$ be the stable $\beta$-Grothendieck polynomial attached to $\lambda$. Each homogeneous component of the $\beta =1$ specialization $G_{\lambda }^{(1)}$ is Schur-positiv…
