Abstract

We first show that the Airy1_1 process is associated using the association property of the solution to the stochastic heat equation and convergence of the KPZ equation to the KPZ fixed point. Then we apply Newman's inequality to establish the ergodicity and central limit theorem for the Airy1_1 process. Combined with the asymptotic behavior of the tail probability, we derive a Poisson limit theorem for the Airy1_1 process and give a precise estimate on the asymptotic behavior of the maximum of the Airy1_1 process over an interval. Analogous results for the Airy2_2 process are also presented.
