The intersection of the spectra of two Sturm–Liouville equations

Applied Mathematics and Computation, 2013
This paper studies the intersection of the spectra for two Sturm-Liouville equations with general separated BCs and real coupled BCs. Under certain conditions, we proved that a two-dimensioned vectorial SLPs with separated BCs only has finitely many double eigenvalues and obtain a bound M"Q depending on Q(x) and its eigenvalues, which are larger than M"

The Sturm–Liouville Equation

2006
Abstract This chapter concerns the homogeneous equation where p : [a, b] → ℝ is continuously differentiable, q : [a, b] → ℝ and ⍴: [a, b] → ℝ are continuous, p(x) > 0 and ⍴(x) > 0, for all x in [a, b], and λ is a real constant.

Inverse spectral problem for the Sturm Liouville equation

Inverse Problems, 2003
Summary: This paper discusses a new numerical approach to computing the potential \(q\) in the Sturm-Liouville problem \(-y''+ qy=\lambda y\) on a compact interval. It is shown that an algorithm to recover \(q\) from eigenvalues and multiplier constants can be derived. Examples of some test problems, and questions of efficiency are discussed.

Sturm Liouville Equations in the frame of fractional operators with exponential kernels and their discrete versions

open access: yesQuaestiones Mathematicae, 2019
In this article, we study Sturm-Liouville Equations (SLEs) in the frame of fractional operators with exponential kernels. We formulate some Fractional Sturm-Liouville Problems (F SLP s) with the differential part containing the left and right sided ...

Preliminaries on Sturm-Liouville Equations

2020
We will consider the second-order linear ordinary differential equation $$\displaystyle -y^{\prime \prime }+q(x)y=\lambda y $$ on a finite or infinite interval. This equation is called the Sturm-Liouville equation, or often the one-dimensional Schro dinger equation .

On the Isospectral Sixth Order Sturm-Liouville Equation

Journal of Lie Theory, 2013
A sixth-order Sturm-Liouville equation of the form \[ Ly:=-y^{(6)}+(A(z)y'')''+(B(z)y')'+C(z)y=\lambda y, \;\;\;\;a\leq z\leq b, \] is investigated with six end conditions which make a self adjoint problem. The Sturm Liouville operator is factorized as the product of a third order differential operator and its adjoint. It is shown that factorization of

A Coupled System of Sturm–Liouville Differential Equations

Mathematical Notes
In this paper, the authors investigate the existence and the asymptotic behavior of positive continuous solutions of the following nonlinear coupled system: \[ \left\{ \begin{array}{c} -\frac{1}{A}(Au')'=a(x)u^pv^r \quad \text{on}\ (0,1)\\ -\frac{1}{B}(Bu')'=b(x)u^qv^s\quad \text{on}\ (0,1),\\ u(0)=u(1)=v(0)=v(1)=0, \end{array} \right. \] where \(p, q \
