Definition
The Fredholm integral equations are integral equations of the first and second kind such that the limits of integration are constant:
Fredholm Integral Equation of the First Kind
A Fredholm integral equation of the first kind is an integral equation of the form:
- $\ds \map f x = \lambda \int_a^b \map K {x, y} \map g y \rd y$
where $g$ is an unknown real function.
Fredholm Integral Equation of the Second Kind
A Fredholm integral equation of the second kind is an integral equation of the form:
- $\ds \map g x = \map f x + \lambda \int_a^b \map K {x, y} \map g y \rd y$
Also known as
The Fredholm integral equations can also be seen in the form Fredholm's integral equations.
