Spatial fluctuation for stochastic heat equation with Hölder coefficients
Carl Mueller, Fei Pu
In this paper, we establish associativity, spatial ergodicity and a central limit theorem for certain nonnegative solutions to the stochastic heat equation $\partial_t u=\frac12\pa…

Macroscopic Hausdorff dimension of the level sets of the Airy processes
Sudeshna Bhattacharjee, Fei Pu
We study the Macroscopic Hausdorff dimension of the upper and lower level sets of the Airy processes, following the general method developed in Khoshnevisan et al. \cite{KKX17}. Fo…

Ergodicity, CLT and asymptotic maximum of the Airy process
Fei Pu
We first show that the Airy process is associated using the association property of the solution to the stochastic heat equation and convergence of the KPZ equation to the KPZ…
