Monomial realization conjecture for generalized minors and Demazure crystals
Monomial realization conjecture for generalized minors and Demazure crystals
Let be the index set of the root system, let be a reduced expression of the longest Weyl-group element, and let be the associated integer data. For each , let , , , , and the generalized minors and be as in the preceding construction. Let and be Demazure crystals, and let denote the monomial corresponding to in the monomial realization associated with . Monomial realization conjecture. There exists a reduced expression of the longest Weyl-group element and data such that, for every , there are Demazure crystals and and positive integers and satisfying
and
The conjecture proposes a simultaneous Demazure-crystal monomial expansion for the two generalized minors arising from the decorated geometric-crystal construction. It extends the explicitly verified type examples and would connect generalized minors, geometric crystals, and monomial realizations of crystal bases; the source provides no resolution.
