Let $\mathbb{P}\underline{\mathrm{S}}^d_n$ be the projective space of all multiaffine homogeneous real stable polynomials of degree $d$ in $n$ variables. Ball conjecture. The space…

Let $p,q \in \mathbb{R}_+[x_1,\ldots,x_n]$ be homogeneous real stable polynomials of total degree $d$. For a multi-index $\mu$ with $|\mu|=d$, write $p_\mu$ and $q_\mu$ for the cor…
