Query: Combinatorics hidden in hyperbolic polynomials and related topics   The main topic of this paper is various "hyperbolic" generalizations of the
Edmonds-Rado theorem on the rank of intersection of two matroids. We prove
several results in this direction and pose a few questions. We also give
generalizations of the Obreschkoff theorem and recent results of J. Borcea and
B. Shapiro.
