Numerical solution of Fredholm integral equations of first kind
Oxford University, Computing Laboratory, 9 South Parks Road, Oxford, UK
The solution of Fredholm integral equations of the first kind is considered in terms of a linear combination of eigenfunctions of the kernel. Practical and theoretical difficulties appear when any corresponding eigenvalue is very small, and practical solutions are obtained which exclude the small eigensolutions and which are exact for a slightly perturbed integral equation. Methods are discussed for simplifying the computation of the relevant eigensolutions, and four numerical examples are treated in detail.
