History of integral equation J. Fourier is the initiator of the theory of integral equations.
A term integral equation first suggested by Du Bois-Reymond in Du Bois-Reymond define an integral equation is understood an equation in which the unknown function occurs under one or more signs of definite integration. Late eighteenth and early ninetieth century Laplace, Fourier, Poission, Liou- ville and Able studies some special type of integral equation. The pioneering systematic investigations goes back to late nineteenth and early twentieth century work of volterra, Fredholm and Hilbert.
In , Volterra published a series of famous papers in which he singled out the notion of a functional and pioneered in the development of a theory of functional s in theory of linear integral equation of special type.
This paper became famous almost overnight and soon took its rightful place among the gems of modern mathematics.
Functional A functional is a generalization of the notion of a function of a finite number of numerical variables, defined by Aristotle D. Integral equation Integral equation is an equation in which the unknown, say a function of a numerical variable, occurs under an integral. That means a functional equation involving the unknown function under one or more integrals.
Main difference between Volterra and Fredholm Integral equations are range of integration in the integral equation. First one has finite range and other has variable range.
There are two way to think about this integral equation according to domain. Case 1.
This equation look like a Fredholm integral equation. Case 2. So such type of integral equation called Non homogeneous linear Volterra - Fredholm integral equation.
Solution of integral equation A solution of integral equation is a function that satisfies the original integral equation. Verify that the given functions are solutions of the corresponding integral equations and check it kinds. First, let us notice that the right-hand side of Eq.
After this Eqs. Construction of the solution of Volterra integral equation In previous section we showed an initial value problem of differential equa- tion is equivalent to Volterra integral equation. First idea to solve such type of problems, we convert this problem in an initial value problem of differen- tial equation.
After this the solution of initial value problem of differential equation is the required solution. There are several way to construct the solution, we are going to illustrate some of then as follows.
Existence and uniqueness solution for Volterra integral equation Theorem 5. The potential theory contributed more than any field to give rise to integral equations. Mathematical physics models, such as diffraction problems, scattering in quantum mechanics, conformal mapping, and water waves also contributed to the creation of integral equations.
This process is experimental and the keywords may be updated as the learning algorithm improves.

Then, there exists a unique continuous solution y x of Eq. Classification of Integral Equations Integral equations appear in many types. In this text we will be concerned on the following types of integral equations .
Volterra started working on integral equations in , but his serious study began in An integral equation are encountered in various fields of science and numerous applications in elasticity, plasticity, electrodynamics, electrical engineering, heat and mass transfer, economics, approximation theory, filtration theory, fluid dynamics, electrostatics, biomechanics, game theory, control, queuing theory, medicine, etc. To browse Academia.
