##### Integral equations - Definition
In mathematics , an integral equation is an equation in which an unknown function appears under an integral sign. There is a close connection between differential and integral equations, and some problems may be formulated either way. Integral equations are classified in three ways. There are thus eight kinds of integral equations.
• If the limits of integration are fixed, it is called a Fredholm equation . If one limit of integration is variable, it is called a Volterra equation If the unknown function appears only under the integral sign, it is called an integral equation of the first kind .

The most basic type of integral equation is a Fredholm equation of the first type The notation follows Arfken . Here φ is an unknown function, f is a known function, and K is another known function of two variables, often called the kernel function. Note that the limits of integration are constant; this is what characterizes a Fredholm equation. If the unknown function occurs both inside and outside of the integral, it is known as a Fredholm equation of the second type The parameter λ is an unknown factor, which plays the same role as the eigenvalue in linear algebra If one limit of integration is variable, it is called a

##### Introduction
Integral equations, naturally, seek functions which satisfy relationships with their integrals. For example, the value of a function at each time may be related to its average value over all preceding time. Included in this area are equations mixing integration and differentiation. Many of the themes from differential equations recur: qualitative questions, methods of approximation, specific types of equations of interest, transforms and operators useful for simplifying the problems.

##### Integral Equations
by numerical-methods.com In their simplest form, integral equations are equations in one variable (say t) that involve an integral over a domain of another variable (s) of the product of a kernel function K(s,t) and another (unknown) function (f(s)). The purpose of the numerical solution is to determine the unknown function f. If the limit(s) on the integration domain are fixed then it is said to be a Fredholm Equation. If the limit(s) on the integration domain are not fixed then it is said to be a Volterra Equation. Integral equations are solved by replacing the integral by a numerical integration or quadrature formula . The integral equation is then reduced to a linear equation with the values of f at the quadrature points being unknown at the outset. The solution of the linear equation(s) gives the approximate values of f at the quadrature points. Fredholm Equations Fredholm equations occur in two forms: Fredholm equations of the first kind and Fredholm equations of the second kind. There is a close analogy between Fredholm equations and linear systems of equations ; the functions can be viewed as vectors, the integration over the kernel function as a matrix. The solution generally involves replacing the integral equation by a linear system and then solving it. Clearly the accuracy of this method depends partially on the accuracy of the numerical integration method; the more quadrature points the better.

##### Differential Equations and integral equations and Operators
Return to start of tour Up to Mathematical Analysis In these areas we seek to find properties of functions f knowing relationships between f and its derivatives or integrals; this includes the study of differential operators and their applications in mathematics. As can be seen from their position on the MathMap, these parts of Analysis are intimately connected with many of the applications of mathematics, particularly to parts of mathematical physics.
• 34: Ordinary differential equations are equations to be solved in which the unknown element is a function, rather than a number, and in which the known information relates that function to its derivatives. Few such equations admit an explicit answer, but there is a wealth of qualitative information describing the solutions and their dependence on the defining equation. There are many important classes of differential equations for which detailed information is available. Applications to engineering and the sciences abound. Today, numerical solutions are actively studied.
• 35: Partial differential equations begin with much the same formulation as ordinary differential equations, except that the functions to be found are functions of several variables. Again, one generally looks for qualitative statements about the solution. For example, in many cases, solutions exist only if some of the parameters lie in a specific set (say, the set of integers). Various broad families of PDE's admit general statements about the behaviour of their solutions. This area has a long-standing close relationship with the physical sciences, especially physics, thermodynamics, and quantum mechanics.

##### A Boundary Integral Equation Package
BIEPACK is a package of programs, written in Fortran 77, which can be used to solve integral equations defined over a surface S in R . The package contains two kinds of programs. First, utility programs are given to help with the creation and refinement of triangulations over the surface of S , numerical integration, interpolation, and approximation over S , and approximation of S using quadratic interpolation. Other utilities are also included. The second kind of program in the package is to carry out the solution of particular types of integral equations. For example, the program neumann_ell.f solves a second kind integral equation that is a reformulation of the exterior Neumann problem for Laplace's equation over an ellipse, and the program is easily modified for other surfaces. Two versions of the package have been released, the first in 1993 and the second in 1998. Both are available.
• An introduction to both Version #1 and Version #2 of the program package, describing the different means of obtaining the package. Any comments on the new Version #2 are much appreciated. Links to obtaining the programs are given here, either as a tar file or as individual Fortran programs.
