Relations between spectrum curves of discrete Sturm-Liouville problem with nonlocal boundary conditions and graph theory

open access: yesLietuvos Matematikos Rinkinys, 2021
Sturm-Liouville problem with nonlocal boundary conditions arises in many scientific fields such as chemistry, physics, or biology. There could be found some references to graph theory in a discrete Sturm-Liouville problem, especially in investigation of ...

Research on singular Sturm–Liouville spectral problems with a weighted function

open access: yesBoundary Value Problems, 2022
As early as 1910, Weyl gave a classification of the singular Sturm–Liouville equation, and divided it into the Limit Point Case and the Limit Circle Case at infinity. This led to the study of singular Sturm–Liouville spectrum theory. With the development

On an Integral Equation with the Riemann Function Kernel

open access: yesAxioms, 2022
This paper is concerned with a study of a special integral equation. This integral equation arises in many applied problems, including transmutation theory, inverse scattering problems, the solution of singular Sturm–Liouville and Shrödinger equations ...

Perturbation and spectral theory for singular indefinite Sturm–Liouville operators [PDF]

open access: yesJournal of Differential Equations, 2023
We study singular Sturm-Liouville operators of the form \[ \frac{1}{r_j}\left(-\frac{\mathrm d}{\mathrm dx}p_j\frac{\mathrm d}{\mathrm dx}+q_j\right),\qquad j=0,1, \] in $L^2((a,b);r_j)$, where, in contrast to the usual assumptions, the weight functions $

A Study of the Eigenfunctions of the Singular Sturm–Liouville Problem Using the Analytical Method and the Decomposition Technique

open access: yesMathematics, 2020
The history of boundary value problems for differential equations starts with the well-known studies of D. Bernoulli, J. D’Alambert, C. Sturm, J. Liouville, L. Euler, G. Birkhoff and V. Steklov.

Müntz sturm-liouville problems: Theory and numerical experiments [PDF]

open access: yesFractional Calculus and Applied Analysis, 2021
This paper presents two new classes of M ntz functions which are called Jacobi-M ntz functions of the first and second types. These newly generated functions satisfy in two self-adjoint fractional Sturm-Liouville problems and thus they have some spectral properties such as: orthogonality, completeness, three-term recurrence relations and so on.

Elastic Stars in General Relativity: II. Radial perturbations [PDF]

open access: yes, 2003
We study radial perturbations of general relativistic stars with elastic matter sources. We find that these perturbations are governed by a second order differential equation which, along with the boundary conditions, defines a Sturm-Liouville type ...
