Abstract:

We propose and analyze a spectral Jacobi-collocation approximation for frac-tional order integro-differential equations of Volterra type. The fractional derivative is de-scribed in the Caputo sense. We provide a rigorous error analysis for the collection method, which shows that the errors of the approximate solution decay exponentially in L norm and weighted L2-norm. The numerical examples are given to illustrate the theoretical results.

Key words: Spectral Jacobi-collocation method, fractional order integro-differential equa-tions, Caputo derivative
