## Computational results and analysis for a class of linear and nonlinear singularly perturbed convection delay problems on Shishkin mesh

#### A.s.v. Ravi KANTH [1] , P. Murali Mohan KUMAR [2]

This article presents a hybrid numerical scheme for a class of linear and nonlinear singularly perturbed convection delay problems on piecewise uniform. The proposed hybrid numerical scheme comprises with the tension spline scheme in the boundary layer region and the midpoint approximation in the outer region on piecewise uniform mesh. Error analysis of the proposed scheme is discussed and is shown $\varepsilon$-uniformly convergent. Numerical experiments for linear and nonlinear are performed to confirm the theoretical analysis.
