A numerical approach for investigating a special class of fractional Riccati equation

open access: yesResults in Physics, 2020
A computational scheme for solving special type of fractional Riccati equation with singularly perturbed (FRSP) is investigated. It is based on dividing the equation into algebraic equation and fractional equation.

A Hybrid Fitted Mesh Numerical Scheme for Solving Singularly Perturbed Reaction–Diffusion Equation With Mixed Shifts

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This study develops a robust hybrid numerical scheme for a class of time‐dependent, singularly perturbed differential‐difference equations characterized by a small positive parameter multiplying the highest order derivative term and mixed spatial shifts (delay and advance) in the reaction terms.

On a set of singularly perturbed convection–diffusion equations

open access: yesJournal of Computational and Applied Mathematics, 2005
The aim of the material is to study the convergence properties of a first-order upwind difference scheme applied to a weakly coupled system of singularly perturbed convection-diffusion equations: \[ \begin{aligned} -\varepsilon_1 u^{\prime\prime}_1- a_1 u_1'\quad &\text{in }(0,1),\quad u_1(0)= u_1(1)= 0,\\ -\varepsilon_2 u^{\prime\prime}_2- a_2 u_2 ...

Existence of Kink and Antikink Wave Solutions of Singularly Perturbed Modified Gardner Equation

open access: yesMathematics
In this paper, the singularly perturbed modified Gardner equation is considered. Firstly, for the unperturbed equation, under certain parameter conditions, we obtain the exact expressions of kink wave solution and antikink wave solution by using the ...

Singularly perturbed equations of degenerate type

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 2017
This work is devoted to the study of nonvariational, singularly perturbed elliptic equations of degenerate type. The governing operator is anisotropic and ellipticity degenerates along the set of critical points. The singular behavior is of order \text{O}\left(\frac{1}{\epsilon }\right)
