“…For example (x 1 + x 3 ) 2 − x 2 2 is not a stable polynomial but psd-stable where K is the cone of positive semidefinite matrices. See [DGT21] for a comparison among stable, psd-stable and determinantal polynomials. By [JT18b], the hyperbolicity cones of a homogeneous polynomial f coincide with the components of I(f ) c , where I(f ) c denotes the complement of I(f ).…”

“…The proof is based on the observation that a hyperbolic polynomial f ∈ C[z] is K-stable if and only if int K ⊆ I(f ) c . See [DGT21] for the details.…”

“…Recently, various generalizations and variations of the stability notion have been studied, such as stability with respect to a polyball [13,14], conic stability [9,18], Lorentzian polynomials [7], or positively hyperbolic varieties [29]. Exemplarily, regarding the conic stability, a polynomial p ∈ C[z] is called K-stable for a proper cone K ⊂ R n if p(z) = 0, whenever z im ∈ int K, where int is the interior.…”
