Discontinuous Galerkin Methods for Multi-Pantograph Delay Differential Equations
Advances in Applied Mathematics and Mechanics, 2020 Summary: In this paper, the discontinuous Galerkin method is applied to solve the multi-pantograph delay differential equations. We analyze the optimal global convergence and local superconvergence for smooth solutions under uniform meshes. Due to the initial singularity of the forcing term \(f\), solutions of multi-pantograph delay differential ...

Numerical Approach for Solving Fractional Pantograph Equation
International Journal of Computer Applications, 2015 this article, we have investigate a Taylor collocation method, which is based on collocation method for solving fractional pantograph equation. This method is based on first taking the truncated fractional Taylor expansions of the solution function in the mathematical model and then substituting their matrix forms into the equation.
