Abstract
In this paper, the dependence of eigenvalues of one-dimensional Schrödinger operators with point interactions in potentials is studied. More precisely, the second-order Fréchet derivative of eigenvalues of one-dimensional Schrödinger operators with point interactions in potentials is presented.
