In mathematics, an integral equation is an equation in which an unknown function appears under an integral sign.
Description
There is a close connection between differential equations and integral equations, and some problems may be formulated either way. See, for example:
- Green's function
- Fredholm theory
- Maxwell's equations
Numerical solutions
It is worth noting that integral equations often do not have an analytical solution, and must be solved numerically.
An example of this is evaluating the Electric-Field Integral Equation (EFIE) or Magnetic-Field Integral Equation (MFIE) over an arbitrarily shaped object in an electromagnetic scattering problem.
