The Gaussian structure of a perturbed KPZ

Yu Gu, Tomasz Komorowski

We study the KPZ equation on a circle with an additive spatial perturbation , where is a spacetime white noise and is a s…

Spatial decorrelation of KPZ from narrow wedge

Yu Gu, Fei Pu

We study the spatial decorrelation of the solution to the KPZ equation with narrow wedge initial data. For fixed , we determine the decay rate of the spatial covariance functi…

Noise sensitivity for stochastic heat and Schrödinger equation

Yu Gu, Tomasz Komorowski

In this note, we consider the stochastic heat and Schrödinger equation, and show that, at time , the onset of the chaos occurs on the scale of , and the Fourier spectrum of…

Integration by parts and invariant measure for KPZ

Yu Gu, Jeremy Quastel

Using Stein's method and a Gaussian integration by parts, we provide a direct proof of the known fact that drifted Brownian motions are invariant measures (modulo height) for the K…

Periodic Pitman transforms and jointly invariant measures

Ivan Corwin, Yu Gu, Evan Sorensen

We construct explicit jointly invariant measures for the periodic KPZ equation (and therefore also the stochastic Burgers' and stochastic heat equations) for general slope paramete…

Some recent progress on the periodic KPZ equation

Yu Gu, Tomasz Komorowski

We review recent progress on the study of the Kardar-Parisi-Zhang (KPZ) equation in a periodic setting, which describes the random growth of an interface in a cylindrical geometry.…

Stationary patterns and their selection mechanism of Urban crime models with heterogeneous near-repeat victimization effect

Yu Gu, Qi Wang, Guangzeng Yi

In this paper, we study two PDEs that generalize the urban crime model proposed by Short \emph{et al}. [Math. Models Methods Appl. Sci., 18 (2008), pp. 1249-1267]. Our modification…
