Invariant densities for random continued fractions [PDF]

open access: yes, 2022
We continue the study of random continued fraction expansions, generated by random application of the Gauss and the Rényi backward continued fraction maps.

Dynamics of Non-Autonomous Stochastic Semi-Linear Degenerate Parabolic Equations with Nonlinear Noise

open access: yesMathematics, 2023
In the present paper, we aim to study the long-time behavior of a stochastic semi-linear degenerate parabolic equation on a bounded or unbounded domain and driven by a nonlinear noise.

Lower semicontinuity of attractors for non-autonomous dynamical systems [PDF]

open access: yes, 2009
This paper is concerned with the lower semicontinuity of attractors for semilinear non-autonomous differential equations in Banach spaces. We require the unperturbed attractor to be given as the union of unstable manifolds of time-dependent hyperbolic

Gradient Infinite-Dimensional Random Dynamical Systems [PDF]

open access: yes, 2012
In this paper we introduce the concept of a gradient random dynamical system as a random semiflow possessing a continuous random Lyapunov function which describes the asymptotic regime of the system.

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 ...

H1-Random Attractors and Asymptotic Smoothing Effect of Solutions for Stochastic Boussinesq Equations with Fluctuating Dynamical Boundary Conditions

open access: yesAbstract and Applied Analysis, 2013
This work is concerned with the random dynamics of two-dimensional stochastic Boussinesq system with dynamical boundary condition. The white noises affect the system through a dynamical boundary condition.

Stability analysis of the projectile based on random center manifold reduction

open access: yesTheoretical and Applied Mechanics Letters, 2023
The center manifold method has been widely used in the field of stochastic dynamics as a dimensionality reduction method. This paper studied the angular motion stability of a projectile system under random disturbances.

(L2,H1)-Random Attractors for Stochastic Reaction-Diffusion Equation on Unbounded Domains

open access: yesAbstract and Applied Analysis, 2013
We study the random dynamical system generated by a stochastic reaction-diffusion equation with additive noise on the whole space ℝn and prove the existence of an (L2,H1)-random attractor for such a random dynamical system. The nonlinearity f is supposed

A central limit theorem for random dynamical systems

open access: yes上海师范大学学报. 自然科学版, 2019
In this article, we establish a central limit theorem (CLT) for random dynamical systems (RDS), which is a supplement to the ergodic theory of random dynamical system.

Asymptotic Behavior of Stochastic Partly Dissipative Lattice Systems in Weighted Spaces

open access: yesInternational Journal of Differential Equations, 2011
We study stochastic partly dissipative lattice systems with random coupled coefficients and multiplicative/additive white noise in a weighted space of infinite sequences.
