Abstract

We prove that the expected value and median of the supremum of L2L^2 normalized random holomorphic fields of degree nn on mm-dimensional K\"ahler manifolds are asymptotically of order mlogn\sqrt{m\log n}. This improves the prior result of Shiffman-Zelditch (arXiv:math/0303335) that the upper bound of the media is of order logn\sqrt{\log n} The estimates are based on the entropy methods of Dudley and Sudakov combined with a precise analysis of the relevant pseudo-metric and its covering numbers, which can be precisely evaluated using off-diagonal asymptotics of Bergman kernels. Recent work of the authors on the value distribution of these fields are also used to get precise constants.
