Spectral-Collocation Methods for Fractional Pantograph Delay-Integrodifferential Equations [PDF]

Advances in Mathematical Physics, 2013
We propose and analyze a spectral Jacobi-collocation approximation for fractional order integrodifferential equations of Volterra type with pantograph delay. The fractional derivative is described in the Caputo sense. We provide a rigorous error analysis

Superconvergence of spectral collocation method for initial value problem of ordinary differential equations

上海师范大学学报. 自然科学版, 2021
In this paper, we study the spectral collocation method for the initial value problems of ordinary differential equations. Based on Legendre-Gauss points, we propose the spectral collocation method for the initial value problems of first-order and second-

Spectral collocation methods [PDF]

Applied Numerical Mathematics, 1989
This is a survey article on the application of spectral collocation methods to the solution of partial differential equations. For the most part, the basis functions used are either trigonometric or Chebyshev polynomials, although there is some discussion of Legendre polynomials.

Efficient Spectral Collocation Method for Tempered Fractional Differential Equations

Fractal and Fractional, 2023
Transient anomalous diffusion may be modeled by a tempered fractional diffusion equation. In this paper, we present a spectral collocation method with tempered fractional Jacobi functions (TFJFs) as basis functions and obtain an efficient algorithm to ...
