Comparative Study on Numerical Methods for Singularly Perturbed Advanced-Delay Differential Equations

Journal of Mathematics, 2021
In this paper, we consider a class of singularly perturbed advanced-delay differential equations of convection-diffusion type. We use finite and hybrid difference schemes to solve the problem on piecewise Shishkin mesh.
