Numerical results for linear Fredholm integral equations of the first kind over surfaces in 3D
Résumé
Linear Fredholm integral equations of the first kind over surfaces are less familiar than those of the second kind, although they arise in many applications like computer tomography, heat conduction, and inverse scattering. This article emphasizes their numerical treatment, since discretization usually leads to ill-conditioned linear systems. Strictly speaking, the matrix is nearly singular and ordinary numerical methods fail. However, there exists a numerical regularization method --- the Tikhonov method --- to deal with this ill-conditioning and to obtain accurate numerical results.
