The Lorentzian conjecture for normalized skew Schur polynomials in partition notation

Let $\lambda,\mu\in\mathbb{Z}_{\geq0}^n$ be partitions satisfying $\lambda_i\geq\mu_i$ for every $i$, and let $s_{\lambda/\mu}$ be the skew Schur polynomial. Skew-Schur conjecture. The normalized polynomial

$$\mathrm{N}(s_{\lambda/\mu})$$

is Lorentzian. The source reports computational tests for partitions of bounded size; the general assertion remains open.
