Web2 INTEGRAL EQUATIONS I De nition: A Volterra integral equation for u(x) has the form u(x) = a+ Z x a k(x;t)u(t)dt: The function k(x;t) is the kernel. Note the integral upper bound is x(the ind. variable). Volterra integral equations are ‘equivalent’ to ODE initial value problems on x afor linear ODEs. They will not be studied here.

WebIn mathematics, the Fredholm integral equation is an integral equation whose solution gives rise to Fredholm theory, the study of Fredholm kernels and Fredholm operators. The integral equation was studied by Ivar Fredholm. A useful method to solve such equations, the Adomian decomposition method, is due to George Adomian .

Web$\begingroup$ This is the approach that comes naturally to me when I see this integral equation.
