| Résume | A real polynomial in one variable is real-rooted if and only if it is the characteristic polynomial of a real symmetric matrix. Hyperbolic polynomials are the multivariate generalizations of real-rooted polynomials and their relation to matrices is far more intricate. A key role is played by interlacing polynomials, whose zeros are nested in between those of a given hyperbolic polynomial. This talk will survey some known results as well as work in progress. |
