Non-Linear Stochastic Partial Differential Equations with Delays: Existence and Uniqueness of Solutions
(1991)
The main aim of this paper is to study stochastic PDE's with delay terms. In fact, we prove existence and uniqueness of solutions (in Itô's sense) for a rather general type of stochastic PDE's with non-linear monotone ...

Asymptotic Behaviour of a Logistic Lattice System
(2014)
In this paper we study the asymptotic behaviour of solutions of a lattice dynamical system of a logistic type. Namely, we study a system of in nite ordinary di erential equations which can be obtained after the spatial ...

Invariant measures for stochastic 3D Lagrangian-averaged Navier–Stokes equations with infinite delay
(Elsevier, 2023-04-05)
In this paper we investigate stochastic dynamics and invariant measures for stochastic 3D Lagrangian-averaged NavierStokes (LANS) equations driven by infinite delay and additive noise. We first use the Galerkin approximations, ...

Weak pullback attractors of setvalued processes
(2003)
Weak pullback attractors are de ned for nonautonomous setvalued processes and their existence and upper semi continuous convergence under perturbation is established. Unlike strong pullback attractors, invariance and ...

The persistence of synchronization under environmental noise
(2005)
It is shown that the synchronization of dissipative systems persists when they are disturbed by additive noise no matter how large the intensity of the noise provided asymptotically stable stationary stochastic solutions ...

Pullback attractors for differential equations with multiple variable delays in Lipschitz nonlinearities
(2013)
We establish the results on the existence of pullback attractors for nonautonomous functional differential equations with multiple delays appearing within nonlinear Lipschitz terms. The results are complementary to ...

Asymptotic exponential stability for diffusion processes driven by stochastic differential equations in duals of nuclear spaces
(2001)
The main objective of this paper is to investigate the asymptotic stability for diffusion processes driven by a class of Itˆo stochastic differential equations in duals of nuclear spaces. A coercivity condition imposed on ...

Existence and Uniqueness of Solutions for Non-Linear Stochastic Partial Differential Equations
(1991)
We state some results on existence and uniqueness for the solution of non linear stochastic PDEs with deviating arguments. In fact, we consider the equation dx(t) + (A(t; x(t)) + B(t; x(¿ (t))) + f(t)) dt = (C(t; x(½(t))) ...

Pullback, forward and chaotic dynamics in 1-D non-autonomous linear-dissipative equations
(IOP Publishing, 2017-01)
The global attractor of a skew product semiflow for a non-autonomous differential equation describes the asymptotic behaviour of the model. This attractor is usually characterized as the union, for all the parameters in ...
