Numerical Simulation of Singularly Perturbed Delay Differential Equations With Large Delay Using an Exponential Spline

In this study, numerical solution of a differential-difference equation with boundary layer at one end the domain is suggested using an exponential spline. The scheme developed spline special type mesh. A fitting parameter inserted in to improve accuracy and control oscillations due large delay. Convergence method examined. error profiles are represented by tabulating maximum absolute errors solution. Graphs being used show that how influence structure.
