Li's contraction interlacing conjecture for matroid Chow polynomials
Let be a geometric lattice, let be an atom of , and let and denote the augmented and ordinary Chow polynomials of the upper interval , with and the corresponding polynomials of . Li's conjecture. The augmented and ordinary Chow polynomials of the upper interval interlace those of :
Equivalently, for any simple matroid on ground set and any , contraction satisfies and . The source describes this as a strengthening of the Chow-polynomial real-rootedness conjecture and gives no resolution.
