Marchenko equation
In mathematical physics, more specific in the one-dimensional inverse scattering problem, the Marchenko equation, named after Vladimir Marchenko, is derived by computing the Fourier transform of the scattering relation:
where
is a symmetric kernel, so that
which is computed from the scattering data. Solving the Marchenko equation one obtains the kernel of the transformation operator from which the potential can be read off.
This equation is derived from the Gel'fand-Levitan integral equation, using the Povzner-Levitan representation.
