報(bào)告摘要:
In this talk, I will present the spatial decorrelation of the solution to the KPZ equation with narrow wedge initial data. For fixed t, we determine the decay rate of the spatial covariance function. In addition, we prove that the finite-dimensional distributions of the properly rescaled spatial average of the height function converge to those of a Brownian motion. This is based on a joint work with Yu Gu.
