A different approach for solving the nonlinear Fredholm integral equations of the second kind. (English) Zbl 1092.65117
The authors discuss a method for finding an approximate solution of the nonlinear Fredholm integral equation of the second kind $x(t)=y(t)+\int_a^b k(t,s,x(s))\,ds,\quad\text{a.e. on }[a,b]$ First, the problem under consideration is converted to an optimal control problem by introducing an artificial control function. Then a linear programming problem is formulated by using some concepts of measure theory. The solution of this linear programming problem provides the approximate solution of the Fredholm integral equation. It is shown that the nonlinearity of the kernel has no serious effect on the convergence of the solution. Some examples are given to illustrate the applicability of the method.
