The Lommel differential equation, named after Eugen von Lommel, is an inhomogeneous form of the Bessel differential equation:

Solutions are given by the Lommel functions sμ,ν(z) and Sμ,ν(z), introduced by Eugen von Lommel (1880),

where Jν(z) is a Bessel function of the first kind and Yν(z) a Bessel function of the second kind.
