A Sturm-Liouville problem with a discontinuous coefficient and containing an eigenparameter in the boundary condition [PDF]

open access: yes, 2013
We study a Sturm-Liouville operator with eigenparameter-dependent boundary conditions and transmission conditions at two interior points. We give an operator-theoretic formulation, construct fundamental solutions, investigate some properties of the ...

Special functions and generalized Sturm-Liouville problems

open access: yes, 2020
This book discusses theoretical and applied aspects of Sturm-Liouville theory and its generalization. It introduces and classifies generalized Sturm-Liouville problems in three different spaces: continuous, discrete, and q-discrete spaces, focusing on ...

Inverse Sturm-Liouville problems with fixed boundary conditions

open access: yesElectronic Journal of Differential Equations, 2015
Necessary and sufficient conditions for two sequences $\{\mu_n\}_{n=0}^\infty$ and $\{ a_n\}_{n=0}^\infty$ to be the spectral data for a certain Sturm-Liouville problem are well known.

On Hochstadt-Lieberman Theorem For Sturm-Liouville Operators

open access: yes, 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).

Approximate solution for Euler equations of stratified water via numerical solution of coupled KdV system

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
We consider Euler equations with stratified background state that is valid for internal water waves. The solution of the initial-boundary problem for Boussinesq approximation in the waveguide mode is presented in terms of the stream function.

Recovering the Sturm-Liouville Operator with Singular Potential Using Nodal Data

open access: yes, 2011
The paper deals with the Sturm-Liouville operator with singular potential. We assume that the potential is a sum of an a priori known distribution from a certain class and an unknown sufficiently smooth function.

NONLINEAR SINGULAR STURM-LIOUVILLE PROBLEMS WITH IMPULSIVE CONDITIONS [PDF]

open access: yes, 2019
In this paper, we consider a non-linear impulsive Sturm-Liouville problem on semiinfinite intervals in which the limit-circle case holds at infinity for THE Sturm-Liouville expression.

On characteristic functions of equilateral regular star-trees [PDF]

open access: yesМатематичні Студії, 2012
A spectral problem generated by the Sturm-Liouville equation on the edges of a regular equilateral finite star-tree with the Dirichlet boundary conditions at the pendant vertices and continuity and Kirchhoff's conditions at the interior vertices is ...

Inverse Problems for the Quadratic Pencil of the Sturm-Liouville Equations with Impulse

open access: yesAbstract and Applied Analysis, 2013

Linear second-order problems with Sturm-Liouville-type multi-point boundary conditions

open access: yesElectronic Journal of Differential Equations, 2012
We consider the eigenvalue problem for the equation $-u'' = lambda u$ on $(-1,1)$, together with general Sturm-Liouville-type, multi-point boundary conditions at $pm 1$. We show that the basic spectral properties of this problem are similar to those
