Pullback exponential attractors for differential equations with delay
(American Institute of Mathematical Sciences, 2021-01-01)
We show the existence of an exponential attractor for non-autono-mous dynamical system with bounded delay. We considered the case of strong dissipativity then prove that the result remains for the weak dissipativity. We ...

Convergence and Approximation of Invariant Measures for 2 Neural Field Lattice Models under Noise Perturbation
(Society for Industrial and Applied Mathematics, 2023-05-09)
This paper is mainly concerned with limiting behaviors of invariant measures for neural field latticemodels in a random environment. First of all, we consider the convergence relation of invariantmeasures ...

On the stochastic threshold of the COVID-19 epidemic model incorporating jump perturbations
(Elsevier, 2023-10-05)
This work delves into the intricate realm of epidemic modeling under the influence of unpredictable surroundings. By harnessing the power of white noise and Lévy noise, we construct a robust framework to capture the ...

STABILITY ANALYSIS OF A DELAY DIFFERENTIAL KALDOR’S MODEL WITH GOVERNMENT POLICIES
(Mathematica Scandinavica [Independent Journal], 2020-03-29)
This paper is devoted to analyze the stability of the economy according to an extended version of Kaldor's economic growth model. We consider the role of the government and its simultaneous monetary and scal policies and ...

Minimizing the expected time to detect a randomly located lost target using 3-dimensional search technique
(Taylor and Francis, 2020)
This paper considers a new model in search theory to find a randomly located target in the 3-dimensional space. An approximation algorithm that facilitates searching procedures for searchers or robots is presented. The ...

Optimal control of a chemotaxis equation arising in angiogenesis
(AIMS Press, 2021-11)
In this paper we consider an optimal control for an equation that models a crucial step in the tumor development, the angiogenesis. We show the existence of an optimal control, we characterize the optimal control as a ...

Stability of fractionally dissipative 2D quasi-geostrophic equation with infinite delay
(Springer, 2020-08-18)
In this paper, fractionally dissipative 2D quasi-geostrophic equations with an external force containing infinite delay is considered in the space Hs with s ≥ 2 − 2α and α ∈ ( 1 2 , 1). First, we investigate the existence ...

Boundary controllability of a one-dimensional phase-field system with one control force
(Elsevier, 2020-03-21)
In this paper, we present some controllability results for linear and nonlinear phase-field systems of Caginalp type considered in a bounded interval of when the scalar control force acts on the temperature equation of ...

Remarks on the control of two-phase Stefan free-boundary problems
(SIAM, 2022-10-11)
This paper concerns the null controllability of the two-phase 1D Stefan problemwith distributed controls. This is a free-boundary problem that models solidification or meltingprocesses. In each ...

Partial stability analysis of stochastic differential equations with a general decay rate
(Springer, 2021-08-28)
This paper is concerned with the almost sure partial practical stability of stochastic differential equations with general decay rate. We establish some sufficient conditions based upon the construction of appropriate ...
