ON ANALYSIS AND DISCRETIZATION OF NONLINEAR ABEL INTEGRAL EQUATIONS OF FIRST KIND
RUDOLF GORENFLO, ANDREAS PFEIFFER
Abstract
For , , we consider the integral equation
under appropriate Lipschitz-like conditions on the function and some of its derivatives, the most essential condition being
After a survey on theorems of existence, uniqueness and stability of the solution we generalize a numerical method, proposed and investigated 1976 by H. W. Branca for the particular case , to all and show it to be convergent for all if the solution is sufficiently smooth. The method is based on piecewise linear interpolation, one-point weighted Gauss quadrature on parition intervals of equal lenght , and collocation.
