Second-order robust finite difference method for singularly perturbed Burgers' equation [PDF]

open access: yesHeliyon, 2022
In this paper, a second-order robust method for solving singularly perturbed Burgers' equation were presented. To find the numerical approximation, we apply the quasilinearization technique before formulation of the scheme.

On the dynamics of a class of difference equations with continuous arguments and its singular perturbation

open access: yesAlexandria Engineering Journal, 2023
The dynamical properties of a class of difference equations with continuous arguments of the form x(t)=g(x(t-r1),x(t-r2)) and its singularly perturbed counterpart ∊dxdt=-x(t)+g(x(t-r1),x(t-r2)) are investigated here.

Computing singularly perturbed differential equations [PDF]

open access: yesJournal of Computational Physics, 2018
A computational tool for coarse-graining nonlinear systems of ordinary differential equations in time is discussed. Three illustrative model examples are worked out that demonstrate the range of capability of the method. This includes the averaging of Hamiltonian as well as dissipative microscopic dynamics whose `slow' variables, defined in a precise ...

On the dynamics of the singularly perturbed of the difference equation with continuous arguments corresponding to the Hénon map

open access: yesAlexandria Engineering Journal, 2023
The Hénon map was introduced by Hénon. It is a very rich dynamical model as Hénon himself proved and compared the dynamical properties of his map with those of other dynamical systems such as the Ro¨ssler model.

Asymptotic Convergence of the Solution of a Singularly Perturbed Integro-Differential Boundary Value Problem

open access: yesMathematics, 2020
In this study, the asymptotic behavior of the solutions to a boundary value problem for a third-order linear integro-differential equation with a small parameter at the two higher derivatives has been examined, under the condition that the roots of the ...
