We say that the multi-affine polynomial P(z1, . . . , zm, w1, . . . , wn) is Grace-like if it does not vanish when {z1, . . . , zm is separated from {w1, . . . , wn) by a circle in the complex plane. Such polynomials have many unexpected probabilistic properties related to the work of Borcea-Brändén.
