Abstract

We study the two-point correlation Knm(z,w)K^m_n(z,w) between zeros and critical points of Gaussian random holomorphic sections sns_n over K\"ahler manifolds. The critical points are points hnsn=0\nabla_{h^n} s_n=0 where hn\nabla_{h^n} is the smooth Chern connection with respect to the Hermitian metric hnh^n on line bundle LnL^n. The main result is that the rescaling limit of Knm(z0+un,z0+vn)K^m_n(z_0+\frac u{\sqrt n}, z_0+\frac v{\sqrt n}) for any z0Mz_0\in M is universal as nn tends to infinity. In fact, the universal rescaling limit is the two-point correlation between zeros and critical points of Gaussian analytic functions for the Bargmann-Fock space of level 11. Furthermore, there is a 'repulsion' between zeros and critical points for the short range; and a 'neutrality' for the long range.
