摘要：

A coupled system of singularly perturbed delay differential equations is solved via nonstandard method in this paper. The denominator function of second order derivative is obtained systematically from the properties of governing equations. The proposed method is found to be uniformly convergent in connection with the perturbation parameter and the error estimates are derived. Numerical results are analysed and it is found the results are agreeing with the theoretical results. © 2021, The Author(s), under exclusive licence to Springer Nature India Private Limited.
