It is shown that the eigenfunctions of the Schrödinger operator on the half-line satisfy an explicitly constructed differential equation with respect to the spectral parameter. Such an equation was earlier obtained for orthogonal polynomials. An analog of the Freud equation is found.
Keywords: one-dimensional Schrödinger equation, eigenfunctions of the Schrödinger equation, spectral function.
Mots-clés : Freud equation
