Numerical treatment of singularly perturbed turning point problems with delay in time
Copyright policy )Numerical treatment of singularly perturbed turning point problems with delay in time
The paper is devoted to the development of a numerical method for analyzing turning point problems for partial differential equations with delay terms and singular perturbations. The method is based on a Crank-Nicolson type discretization in time in combination with a spline approximation using a Shishkin mesh in space. An error analysis (under seemingly relatively strict smoothness conditions) is provided.
