Integral operators, eigenfunctions, perturbation expansion, autonomy
In this paper, we focus on the autonomy issue in the perturbation expansions of eigenfunctions. We consider the zero interval limit perturbation expansion of a Hilbert-Schmidt Integral Operator here and the autonomy means that the eigenfunction depends on the perturbation parameter not only through the independent variable argument but via an additional argument which just the perturbation parameter. Our purpose is to show that the autonomy puts an important restriction on the kernel of the operator and the resulting perturbation series fails to exist unless a specific and appropriate kernel is used. The proof is also supported by the given illustrative implementations.
