  We prove that Schur classes of nef vector bundles are limits of classes that
have a property analogous to the Hodge-Riemann bilinear relations. We give a
number of applications, including (1) new log-concavity statements about
characteristic classes of nef vector bundles (2) log-concavity statements about
Schur and related polynomials (3) another proof that normalized Schur
polynomials are Lorentzian.
