摘要
We are interested in the numerical solution of second kind integral equations of Mellin convolution type. We describe a modified Nystrom method based on the Gauss-Lobatto or Gauss-Radau quadrature rule. Under certain assumptions on the Mellin kernel, we prove the stability and the convergence of the proposed procedure and also derive error estimates. Finally, some test problems are solved and the numerical results showing the effectiveness of our method are presented. (C) 2017 IMACS. Published by Elsevier B.V. All rights reserved.
