Mar 18 at 18:35 | comment | added | Vladimir Dotsenko | @AlexanderBraverman In arxiv.org/abs/2112.12436 Nicolas Perrin and Maxim Smirnov state, in Lemma 4.6, part 3, a simple formula for the degree of the Schubert class corresponding to the root $\alpha$, leading to a simple formula for the Poincaré polynomial. (They refer to the article cited in my answer where this formula is not proved, but I think it should be easy to prove it directly - I just do not have time for this at the moment.) | |
