Unimodality and log-concavity conjecture for Mather polynomials. The polynomial $M_w$ has strictly positive coefficients and is unimodal. If in addition…

Let $X=G/P$ be a cominuscule space, and let $v,w\in W^P$. Write the Mather class of the Schubert variety $X_w^P$ as … The local Euler obstruction coefficients $e_{w,v}$ are non-neg…
