Abstract:
A numerical method to solve a Fredholm integral equation of the second
kind is studied. This approach is based on a collocation method and
Sloan iterations. Our solution is represented by a linear combination
of minimal splines, and the coefficients are calculated by a method of
local approximation (quasi-interpolation). The results of numerical experiments
demonstrating how the quality of approximation can be improved by using minimal
trigonometric splines and corresponding functionals in comparison with several
earlier suggested approaches are presented.
