A Fredholm integral equation of the first kind is an integral equation of the form (1) where is the kernel and is an unknown function to be solved for (Arfken 1985, p. 865). If the kernel is of the special form and the limits are infinite so that the equation becomes ϕ(x) − λ∫ DK(x, s)ϕ(s) ds = f(x) be a Fredholm integral equation of the second kind, where λ is a complex number, f(x) is a known vector function, ϕ(x) is an unknown vector function, K(x, s) is the kernel of equation (1), and D is a domain in some m - dimensional Euclidean space. The solution to a general Fredholm integral equation of the second kind is called an integral equation Neumann series.

The Fredholm Integral Operator, denoted by K, is de ned as on functions f2C([a;b]) as Kf:= Z b a k(x;y)f(y)dy where k is an F.I.E. kernel. Note that Kis a linear operator. The F.I.E. is then written f= g+ Kf which can also be written Tf= g+ Kf using the xed point equation Tf= f. Note that Tf 0 = g+ Kf 0 T 2f 0 = T(Tf 0) = T(g+ Kf 0) = g+ K(g+ Kf 0) = g+ Kg+ Kf 0 T 3f 0 = T(T2f

### It is a Fredholm equation because the limits on the integral are constants; if they were variables then the equation would be a Volterra equation.

How to solve this integral equation Fredholm And Volterra Integral Equations Of The Second Kind William H. Press and Saul A. Teukolsky Integral equations are often the best way to formulate physics problems. However, the typical physics stu dent gets almost no training in integral equations, in contrast to differential equations, for example.

The purpose of this paper is to discuss how the above mentioned fast algorithms are related to certain results concerning Fredholm integral equations, Toeplitz equations and orthogonal polynomials. Integral transform method to the solution of a Fredholm integral equation of second kind and numerical approach was implemented by Kassir [12, 13] in solving the rectangular crack problem, while the classic collocation and Galerkin methods were applied by Ioakimidis [14] for solving the plane crack problem subjected to normal load, whereas a perturbation analysis and the complex potential Integral equation has been one of the essential tools for various areas of applied mathematics. In this paper, we review different numerical methods for solving both linear and nonlinear Fredholm integral equations of second kind.
