Abstract
The results of Amir-Corwin-Quastel,Calabrese-Le Doussal-Rosso,Dotsenko,and Sasamoto-Spohn imply that the one-point distribution of the solution of the KPZ equa-tion with the narrow wedge initial condition coincides with that for a multiplicative statistics of the Airy determinantal random point process. Taking Taylor coefficients of the two sides yields moment identities. We provide a simple direct proof of those via a combinatorial match of their multivariate integral representations.
