Abstract

Let LL be a holomorphic line bundle on a compact complex manifold XX of dimension n,n, and let eϕe^{-\phi} be a continuous metric on L.L. Fixing a measure dμd\mu on XX gives a sequence of Hilbert spaces consisting of holomorphic sections of tensor powers of L.L. We prove that the corresponding sequence of scaled Bergman measures converges, in the high tensor power limit, to the equilibrium measure of the pair (K,ϕ),(K,\phi), where KK is the support of dμ,d\mu, as long as dμd\mu is stably Bernstein-Markov with respect to (K,ϕ).(K,\phi). Here the Bergman measure denotes dμd\mu times the restriction to the diagonal of the pointwise norm of the corresponding orthogonal projection operator. In particular, an extension to higher dimensions is obtained of results concerning random matrices and classical orthogonal polynomials.
