Random attractors for stochastic retarded reaction-diffusion equations with multiplicative white noise on unbounded domains

Open Mathematics, 2018
In this paper we investigate the stochastic retarded reaction-diffusion equations with multiplicative white noise on unbounded domain ℝn (n ≥ 2). We first transform the retarded reaction-diffusion equations into the deterministic reaction-diffusion ...

Pullback attractors for lattice FitzHugh-Nagumo systems with fast-varying delays

四川大学学报. 自然科学版, 2021
We investigate the dynamical behavior of lattice FitzHugh-Nagumo equation with fast-varying delays and obtain the existence and uniqueness of pullback attractor for the equation. Generally, studying the attractors of a time-varying delay equation require

Existence and regularity of pullback attractors for a 3D non-autonomous Navier–Stokes–Voigt model with finite delay

Electronic Journal of Qualitative Theory of Differential Equations
In this manuscript previous results [Nonlinearity 25(2012), 905–930] are extended to a non-autonomous 3D Navier–Stokes–Voigt model in which a forcing term contains memory effects.

Pullback attractors for non-autonomous parabolic equations involving Grushin operators

Electronic Journal of Differential Equations, 2010
Using the asymptotic a priori estimate method, we prove the existence of pullback attractors for a non-autonomous semilinear degenerate parabolic equation involving the Grushin operator in a bounded domain.

On the Dimension of Pullback Attractors in Recurrent Neural Networks

Recurrent neural networks trained via the reservoir computing paradigm have demonstrated remarkable success in learning and reconstructing attractors from chaotic systems, often replicating quantities such as Lyapunov exponents and fractal dimensions.
