Dynamics of the stochastic wave equations with degenerate memory effects on bounded domain [PDF]

open access: yesSurveys in Mathematics and its Applications, 2022
In this work, we consider the behavior of long-time dynamics of a random dynamical system generated wave equations with degenerate memory and additive noise, on bounded domain U, with Dirichlet boundary condition, and nonlinear term f(u) with critical ...

Hopf Bifurcation Analysis for a Stochastic Discrete-Time Hyperchaotic System

open access: yesDiscrete Dynamics in Nature and Society, 2015
The dynamics of a discrete-time hyperchaotic system and the amplitude control of Hopf bifurcation for a stochastic discrete-time hyperchaotic system are investigated in this paper.

Exponential attractors for random dynamical systems and applications [PDF]

open access: yes, 2012
The paper is devoted to constructing a random exponential attractor for some classes of stochastic PDE's. We first prove the existence of an exponential attractor for abstract random dynamical systems and study its dependence on a parameter and then ...

Random periodic solutions of random dynamical systems

open access: yesJournal of Differential Equations, 2009
In this paper, we give the definition of the random periodic solutions of random dynamical systems. We prove the existence of such periodic solutions for a $C^1$ perfect cocycle on a cylinder using a random invariant set, the Lyapunov exponents and the pullback of the cocycle.

Stability-preserving model order reduction for linear stochastic Galerkin systems

open access: yesJournal of Mathematics in Industry, 2019
Mathematical modeling often yields linear dynamical systems in science and engineering. We change physical parameters of the system into random variables to perform an uncertainty quantification.

Antagonistic interactions can stabilise fixed points in heterogeneous linear dynamical systems

open access: yesSciPost Physics, 2023
We analyse the stability of large, linear dynamical systems of variables that interact through a fully connected random matrix and have inhomogeneous growth rates.

Dynamics of random spin systems [PDF]

open access: yesPhysica B+C, 1986
We present inelastic neutron scattering experiments on three prototypical random magnets. For the dilute, insulating antiferromagnet Rb/sub 2/Co/sub c/Mg/sub 1-c/F/sub 4/, the randomness has purely geometrical consequences, and the anomalous dynamical behavior which we observe for c close to the magnetic percolation threshold is due to the fractal ...

Random attractors for stochastic lattice dynamical systems with infinite multiplicative white noise [PDF]

open access: yes, 2016
In this paper we investigate the long term behavior of a stochastic lattice dynamical system with a diffusive nearest neighbor interaction, a dissipative nonlinear reaction term, and a different multiplicative white noise at each node. We prove that this

Probability Density Evolution Algorithm for Stochastic Dynamical Systems Based on Fractional Calculus

open access: yesJournal of Mathematics, 2021
With the increasing load and speed of trains, the problems caused by various random excitations (such as safety and passenger comfort) have become more prominent and thus arises the necessity to analyze stochastic dynamical systems, which is important in

Pesin's Formula for Random Dynamical Systems on $R^d$

open access: yes, 2012
Pesin's formula relates the entropy of a dynamical system with its positive Lyapunov exponents. It is well known, that this formula holds true for random dynamical systems on a compact Riemannian manifold with invariant probability measure which is ...
