Chbili–Qazaqzeh's Jones polynomial conjecture for quasi-alternating links

Let $L$ be a prime quasi-alternating link that is not a $(2,n)$-torus link, and write its Jones polynomial as

$$V_L(t)=\sum_{i=n}^{m}c_i t^i.$$

Chbili–Qazaqzeh's conjecture. The coefficients satisfy

$$c_i c_{i+1}<0$$

for all $n\leq i\leq m-1$.

The conjecture extends the known alternating-coefficient property of prime alternating links to prime quasi-alternating links. The source states that it was subsequently proved that, if a quasi-alternating link satisfies this conjecture, then any link obtained from it by the Champernowne–Kofman twisting construction also satisfies it.
