Abstract

An integral equation is a functional equation in which the unknown variable ø appears under an integral sign. In the case of a single independent variable x, a form commonly encountered can be written as

$$g(x)\phi (x)=f(x)+\lambda \int_{a}^{b}{F[x,\xi ;\phi (\xi )]}d\xi \text{ }(a\le x\le b)$$
(10.1-1)

In this expression, f (x) and g(x) are known functions, and ø(x) is to be determined. The form of the functional F is known, λ is a parameter, and the range of integration [a, b] is specified.
