In this work we obtain approximate solutions for Fredholm integral equations of the second kind by means of Petrov–Galerkin method, choosing “regular pairs” of subspaces, { X n, Y n }, which are simply characterized by the positive definitiveness of a correlation matrix. This choice guarantees the solvability and numerical stability of the approximation scheme in an easy way, and the Author: Silvia Alejandra Seminara, María Inés Troparevsky. In general, Fredholm integral equation of first kind arise typically with a compact operator in applications and hence can be notoriously conditioned when solving numerically.
