| Sep 12, 2018 at 14:58 | comment | added | Sam Hopkins | The non-triviality of the KL polynomials comes from the non-smoothness of the corresponding Schubert varieties, so you're kind of asking when do Schubert varieties have singularities. This is controlled to a large degree by the theory of permutation pattern containment. | |
