Abstract In this paper we obtain Green’s function for a regular Sturm-Liouville problem having the eigenparameter in all boundary conditions in which the left one is in quadratic form. We assume no smoothness condition on the potential.

We are concerned with the inverse spectral problem for a quadratic pencil operator. We show that one given spectrum is enough for its reconstruction in the case of one analytic potential. To do so ...

With the help of an auxiliary eigenvalue problem, we deduce some explicit estimates for the periodic and semiperiodic eigenvalues and the lengths of instability intervals for Hill’s equation with symmetric single-well potentials. We also establish

We use the sampling method to compute the eigenvalues of a quadratic pencil. To do so we first prove a non standard representation of the eigensolution that allows us to decompose the characteristic function into Paley-Wiener functions. Numerical exa

In this study, we find asymptotic estimates of eigenvalues for regular Sturm-Liouville problems having the eigenvalue parameter in all boundary conditions with the symmetric single well potential that is symmetric to the midpoint of the related inter
