Bounded random fluctuations on the input flow in chemostat models with wall growth and non-monotonic kinetics
(AIMS Press, 2021-02-04)
This paper investigates a chemostat model with wall growth and Haldane consumption kinetics. In addition, bounded random fluctuations on the input flow, which are modeled by means of the well-known Ornstein-Uhlenbeck ...

The existence and asymptotic behavior of solutions to 3D viscous primitive equations with Caputo fractional time derivatives
(American Institute of Physics, 2023-09-06)
On the one hand, the primitive three-dimensional viscous equations for large-scale ocean and atmosphere dynamics are commonly used in weather and climate predictions. On the other hand, ever since the middle of the last ...

On a terminal value problem for parabolic reaction–diffusion systems with nonlocal coupled diffusivity terms
(Elsevier, 2022-01-10)
In this article, we are interested in investigating the nonlocal nonlinear reaction– diffusion system with final conditions. This problem is called backward in time problem, or terminal value problem which is understood ...

Dynamics and stability analysis for stochastic 3D Lagrangian-averaged Navier-Stokes equations with infinite delay on unbounded domains
(Springer, 2023-11-02)
This paper is devoted to investigating mean dynamics and stability analysis for stochastic 3D Lagrangian-averaged Navier–Stokes (LANS) equations driven by infinite delay on unbounded domains. We first prove the existence ...

On the uniform controllability for a family of non-viscous and viscous Burgers- α systems
(E.D.P. Sciences, 2021-06-24)
In this paper we study the global controllability of families of the so called non-viscous and viscous Burgers- systems by using boundary and space independent distributed controls. In these equations, the usual convective ...

Finite-Dimensionality of Tempered Random Uniform Attractors
(Springer New York, 2021)
Finite-dimensional attractors play an important role in finite-dimensional reduction of PDEs in mathematical modelization and numerical simulations. For non-autonomous random dynamical systems, Cui and Langa (J Differ ...

The maximization of the p-Laplacian energy for a two-phase material
(SIAM Publications Library, 2021)
We consider the optimal arrangement of two diffusion materials in a bounded openset \Omega \subset \BbbR Nin order to maximize the energy. The diffusion problem is modeled by thep-Laplacianoperator. It is well known that ...

p-th moment exponential stability of neutral stochastic pantograph differential equations with Markovian switching
(Elsevier, 2021-11-01)
In this paper we focus on the p-th moment exponential stability of neutral stochastic pantograph differential equations with Markovian switching (NSPDEwMS). By means of the Lyapunov method, we develop some sufficient ...

Stability with respect to a part of the variables of stochastic di erential equations driven by G-Brownian motion
(Springer, 2020-11-01)
In this paper, we investigate the pth moment exponential stability of stochastic dif- ferential equations driven by G-Brownian motion (G-SDEs) with respect to a part of the variables by means of the G-Lyapunov functions ...

Existence of periodic positive solutions to a nonlinear Lotka-Votlerra competition systems
(AGH University of Science and Technology Press, 2020)
We investigate the existence of positive periodic solutions of a nonlinear Lotka-Volterra competition system with deviating arguments. The main tool we use to obtain our result is the Krasnoselskii fixed point theorem. In ...
