内容摘要Abstract:
Weakly singular integral equations of the second kind typically have non smooth solutions, which seriously affects the accuracy of spectral methods. We propose two kinds of nonpolynomial spectral method to overcome the reduction in the numerical accuracy of the spectral methods caused by the singularities of the solutions. Convergence analysis in the −norm is carried out and the exponential convergence rate is obtained. We demonstrate the efficiency of the proposed methods by numerical example.
