Coupling for some partial differential equations driven by white noise [PDF]

open access: yesarXiv, 2004
We prove, using coupling arguments, exponential convergence to equilibrium for reaction--diffusion and Burgers equations driven by space-time white noise. We use a coupling by reflection.

On random measures on the space of trajectories and strong and weak solutions of stochastic equations [PDF]

open access: yesUkrainian Mathematical Journal, 2004, #5, 2005
The random measures on the space of continuous functions are considered. Stationary random measures are described. The weak solutions of the stochastic equations are substituted by the strong measure-valued solutions.

Large Deviations for Stochastic Generalized Porous Media Equations [PDF]

open access: yesarXiv, 2005
The large deviation principle is established for the distributions of a class of generalized stochastic porous media equations for both small noise and short time.

Early warning signs for SPDEs with continuous spectrum

open access: yesEuropean Journal of Applied Mathematics
In this work, we study early warning signs for stochastic partial differential equations (SPDEs), where the linearisation around a steady state is characterised by continuous spectrum. The studied warning sign takes the form of qualitative changes in the

Maximum principle for SPDEs and its applications [PDF]

open access: yesarXiv, 2006
The maximum principle for SPDEs is established in multidimensional $C^{1}$ domains. An application is given to proving the H\"older continuity up to the boundary of solutions of one-dimensional SPDEs.

One Brownian Stochastic Flow [PDF]

open access: yesTheory of Stochastic Processes.- Vol.10 (26), no. 3-4, 2004, pp. 21-25, 2006
The weak limits of the measure-valued processes organized as a mass carried by the interacting Brownian particles are described. As a limiting flow the Arrattia flow is obtained.

A Random Change of Variables and Applications to the Stochastic Porous Medium Equation with Multiplicative Time Noise [PDF]

open access: yesarXiv, 2007
A change of variables is introduced to reduce certain nonlinear stochastic evolution equations with multiplicative noise to the corresponding deterministic equation. The result is then used to investigate a stochastic porous medium equation.

A Khasminskii type averaging principle for stochastic reaction-diffusion equations [PDF]

open access: yesarXiv, 2008
We prove that an averaging principle holds for a general class of stochastic reaction-diffusion systems, having unbounded multiplicative noise, in any space dimension. We show that the classical Khasminskii approach for systems with a finite number of degrees of freedom can be extended to infinite dimensional systems.
