Abstract
The solution y of a weakly singular Volterra equation of the second kind posed on the interval −1 ≤ t ≤ 1 has in general a certain singular behaviour near t = −1: typically, \(|y^{\prime }(t)| \sim (1+t)^{-\mu }\) for a parameter μ ∈ (0, 1). Various methods have been proposed for the numerical solution of these problems, but up to now there has been no analysis that takes into account this singularity when a spectral collocation method is applied directly to the problem. This gap in the literature is filled by the present paper.
