Asymptotics of Polynomials and Eigenfunctions

摘要

We review some recent results on asymptotic properties of polynomials of large degree, of general holomorphic sections of high powers of positive line bundles over Kahler manifolds, and of Laplace eigenfunctions of large eigenvalue on compact Riemannian manifolds. We describe statistical patterns in the zeros, critical points and L~p norms of random polynomials and holomorphic sections, and he influence of the Newton polytope on these patterns. For eigenfunctions, we discuss L~p norms and mass concentration of individual eigenfunctions and their relation to dynamics of the geodesic flow.
