On the Cauchy problem of a degenerate parabolic-hyperbolic PDE with Lévy noise

open access: yesAdvances in Nonlinear Analysis, 2017
In this article, we deal with the stochastic perturbation of degenerate parabolic partial differential equations (PDEs). The particular emphasis is on analyzing the effects of a multiplicative Lévy noise on such problems and on establishing a well ...

Invariant measures for monotone SPDE's with multiplicative noise term

open access: yes, 2012
We study diffusion processes corresponding to infinite dimensional semilinear stochastic differential equations with local Lipschitz drift term and an arbitrary Lipschitz diffusion coefficient.

Stochastic stability and instability of rumor model

open access: yesOpen Mathematics
In this study, we present a stochastic rumor model. The stability of the disease-free equilibrium state and instability of the free equilibrium E0{E}_{0} of stochastic epidemics model are considered with the help of Lyapunov functions.

Existence of the Fomin derivative of the invariant measure of a stochastic reaction--diffusion equation [PDF]

open access: yes, 2014
We consider a reaction--diffusion equation perturbed by noise (not necessarily white). We prove existence of the Fomin derivative of the corresponding transition semigroup $P_t$. The main tool is a new estimate for $P_tD\varphi$ in terms of $\|\varphi\|_{

An almost sure energy inequality for Markov solutions to the 3D Navier-Stokes equations

open access: yes, 2009
We prove existence of weak martingale solutions satisfying an almost sure version of the energy inequality and which constitute a (almost sure) Markov process.Comment: Submitted for the proceedings of the conference "Stochastic partial differential ...

On a Stochastic Partial Differential Equation with a Noisy Term [PDF]

open access: yes, 2004
2000 Mathematics Subject Classification: 60H15, 60H40We review results obtained in [13] and [14] on a one-dimensional Burgers-type stochastic differential equation involving fractional power of the Laplacian in its linear part, perturbed by a white noise

Blowup solutions of Grushin's operator

open access: yes, 1906
In this note, we consider the blowup phenomenon of Grushin's operator. By using the knowledge of probability, we first get expression of heat kernel of Grushin's operator.

Large deviations for 2D-fractional stochastic Navier-Stokes equation on the torus -Short Proof-

open access: yes, 2013
In this note, we prove the large deviation principle for the 2D-fractional stochastic Navier-Stokes equation on the torus under the dissipation order $ \alpha \in [\frac43, 2]$.Comment: Work submitted to CRAS in 08-08 ...

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
