| Abstract: | The Kardar-Parisi-Zhang (KPZ) equation is a nonlinear stochastic differential equation which describes surface growth. We consider the one-dimensional version of the equation with sharp wedge initial conditions. We show that the distributions of the height is written as an integral of a Fredholm determinant.
We discuss a few properties of the solution. In the long time limit it tends to the GUE Tracy-Widom distribution. The first order correction is of t^{-1/3} which is consistent with a recent experiment of liquid crystal turbulence. We also explain the derivation of our results based on the contour integral formula for ASEP by Tracy and Widom.
