PY - 2022 TI - A second order convergent initial value method for singularly perturbed system of differential-difference equations of convection diffusion type JO - Journal of Mathematics and Computer Science SP - 73--83 VL - 25 IS - 1 AB - In this article, a system of second order singularly perturbed delay differential equations of convection diffusion type problem is considered. An asymptotic expansion approximation of the solution is constructed. Further the asymptotic expansion approximation is numerically approximated using the Runge Kutta methods and hybrid finite difference methods. The error estimate is obtained and it is of almost second order. Numerical examples are given to illustrate the present method.
