Schubert polynomials, 132-patterns, and Stanley’s conjecture. (English) Zbl 1397.05205
Summary: Motivated by a recent conjecture of R. P. Stanley [“Some Schubert shenanigans”, Preprint, arXiv:1704.00851] we offer a lower bound for the sum of the coefficients of a Schubert polynomial in terms of 132-pattern containment.
