Dynamics of a stochastic fractional nonlocal reaction-diffusion model driven by additive noise
(AIMS, 2022-07-01)
In this paper, we are concerned with the long-time behavior of stochastic fractional nonlocal reaction-diffusion equations driven by additive noise. We use the techniques of random dynamical systems to transform the ...

Weak Pullback Attractors of Non-Autonomous Difference Inclusions
(Taylor & Francis, 2003)
Weak pullback attractors are defined for non-autonomous difference inclusions and their existence and upper semi continuous convergence under perturbation is established. Unlike strong pullback attractors, invariance and ...

Pullback and Forward Attractors for a Damped Wave Equation with Delays
(2004)
The existence of a pullback (and also a uniform forward) attractor is proved for a damped wave equation containing a delay forcing term which, in particular, covers the models of Sine-Gordon type. The result follows from ...

An augmented mixed finite element method for the Navier-Stokes equations with variable viscosity
(Society for Industrial and Applied Mathematics, 2016)
A new mixed variational formulation for the Navier–Stokes equations with constant density and variable viscosity depending nonlinearly on the gradient of velocity, is proposed and analyzed here. Our approach employs a ...

The effect of a small bounded noise on the hyperbolicity for autonomous semilinear differential equations
(ScienceDirect, 2021-01-01)
In this work, we study permanence of hyperbolicity for autonomous differential equations under nonautonomous random/stochastic perturbations. For the linear case, we study robustness and existence of exponential dichotomies ...

Flux splitting solvers for shallow water equations with source terms
(2003)
In this work we study some finite volume methods for shallow water equations with source terms. We can find flux difference and flux splitting solvers for hyperbolic conservation laws. In this work we analyze flux splitting ...

Characterization of attractors for non-autonomous dynamical systems: Applications to non-dissipative case and ecological models
(2024-02-23)
Esta tesis está dedicada a la exploración de atractores para sistema dinámicos. Nuestro análisis sigue dos enfoques distintos: uno más abstracto, centrándose en atractores no acotados, y otra investigación más aplicada ...
