Numerical Integration of a Class of Singularly Perturbed Delay Differential Equations with Small Shift

International Journal of Differential Equations, 2012
We have presented a numerical integration method to solve a class of singularly perturbed delay differential equations with small shift. First, we have replaced the second-order singularly perturbed delay differential equation by an asymptotically ...

Asymptotic convergence of the solution for singularly perturbed boundary value problem with boundary jumps

Қарағанды университетінің хабаршысы. Математика сериясы, 2018
The article is devoted to study of boundary value problem with boundary jumps for third order linear integro-differential equation with a small parameter at the highest derivatives, provided that additional characteristic equation’s roots have opposite ...

Computational method for singularly perturbed delay differential equations with twin layers or oscillatory behaviour

Ain Shams Engineering Journal, 2015
In this paper, we have presented a computational method for solving singularly perturbed delay differential equations with twin layers or oscillatory behaviour. In this method, the original second order singularly perturbed delay differential equation is

Implicit extended discontinuous Galerkin scheme for solving singularly perturbed Burgers' equations

Mathematical Modelling and Analysis
We present the implicit-modal discontinuous Galerkin scheme for solving the coupled viscous and singularly perturbed Burgers’ equations. This scheme overcomes overshoot and undershoots phenomena in the singularly perturbed Burgers’ equations. We present
