Numerical solution of singularly perturbed parabolic differential difference equations

Қарағанды университетінің хабаршысы. Математика сериясы
This study presents a computational method for the singularly perturbed parabolic differential difference equations with small negative shifts in convection and reaction terms. To handle the small negative shifts, the Taylor series expansion is applied.

Numerical Modeling of a Boundary Value Problem for a Singularly Perturbed Differential Equation with Two Boundary Layers Using the Spectral-Grid Method

Computation
This paper proposes a spectral-grid method based on Chebyshev polynomials of the first kind for the numerical solution of second-order singularly perturbed boundary value problems containing two boundary layers.

A seventh order numerical method for singular perturbed differential-difference equations with negative shift

Nonlinear Analysis, 2011
In this paper, a seventh order numerical method is presented for solving singularly perturbed differential-difference equations with negative shift. In recent papers the term negative shift has been used for delay.
