Abstract

In this paper, we propose and analyze a spectral approximation for the numerical solutions of fractional integro‐differential equations with weakly kernels. First, the original equations are transformed into an equivalent weakly singular Volterra integral equation, which possesses nonsmooth solutions. To eliminate the singularity of the solution, we introduce some suitable smoothing transformations, and then use Jacobi spectral collocation method to approximate the resulting equation. Later, the spectral accuracy of the proposed method is investigated in the infinity norm and weighted L2 norm. Finally, some numerical examples are considered to verify the obtained theoretical results.
