Sturm-Liouville-Operatorfunktionen

, 2016
Many special functions are solutions of both, a differential and a functional equation. We use this duality to solve a large class of abstract Sturm-Liouville equations, initiating a theory of Sturm-Liouville operator functions; cosine, Bessel, and ...

An Extension of a Formula of F. S. Rofe-Beketov

Mathematics
We address the following problem in this study: given a nontrivial solution, y1, of a four-coefficient Sturm–Liouville eigenvalue differential equation, construct a second solution, y2, linearly independent of y1.

Non-trivial solutions for two-point boundary-value problems of fourth-order Sturm-Liouville type equations

Electronic Journal of Differential Equations, 2012
Using critical point theory due to Bonanno [3], we prove the existence of at least one non-trivial solution for a class of two-point boundary-value problems for fourth-order Sturm-Liouville type equations.

On Hochstadt-Lieberman Theorem For Sturm-Liouville Operators

, 2011
The inverse spectral problem of the Sturm-Liouville operator Lq = -d2/dx2 +q(x) is considered, where q(x) is an integrable function on (0,1).

Inverse spectral and inverse nodal problems for energy-dependent Sturm-Liouville equations with delta-interaction

Electronic Journal of Differential Equations, 2015
In this article, we study the inverse spectral and inverse nodal problems for energy-dependent Sturm-Liouville equations with delta-interaction. We obtain uniqueness, reconstruction and stability using the nodal set of eigenfunctions for the given ...
