Adaptive Piecewise Poly-Sinc Methods for Ordinary Differential Equations

open access: yesAlgorithms, 2022
We propose a new method of adaptive piecewise approximation based on Sinc points for ordinary differential equations. The adaptive method is a piecewise collocation method which utilizes Poly-Sinc interpolation to reach a preset level of accuracy for the

Finite Difference and Sinc-Collocation Approximations to a Class of Fractional Diffusion-Wave Equations [PDF]

open access: yesJournal of Applied Mathematics, 2014
We propose an efficient numerical method for a class of fractional diffusion-wave equations with the Caputo fractional derivative of order α. This approach is based on the finite difference in time and the global sinc collocation in space.
