Comments on eigenfunction expansions of discontinuous Sturm-Liouville systems

, 1989
In earlier works [4],[5] we examined the eigenfunctions of Sturm-Liouville systems of the form −y″(x) + q(x)y(x) = λy(x) on a bounded interval having eigenfunctions with jump discontinuities.

Inverse Sturm-Liouville problems: some recent developments

, 2011
We consider numerical methods for obtaining, from spectral data, information on the potentials of Sturm--Liouville operators. In particular, we describe some recent work on methods using an asymptotic correction technique of Paine, de Hoog and Anderssen.

SPECTRAL MATRIX FOR STURM-LIOUVILLE OPERATORS ON TWO-SIDED UNBOUNDED TIME SCALES

, 2013
We establish existence of a spectral matrix for Sturm-Liouville operators on two-sided unbounded time scales. A Parseval equality and an expansion in eigenfunctions formula are obtained in terms of the spectral matrix.

Qualitatively Correct Sturm-Liouville Eigenfunction Approximation

, 1998
In recent years several high quality Sturm-Liouville software packages have been written (e.g., SLEDGE, SLEIGN, the NAG routine SL02FM). All excel at providing eigenfunction estimates at a finite set of points but only the NAG routine provides ...

Relations between spectrum curves of discrete sturm-liouville problem with non-local boundary conditions and graph theory.

, 2020
Sturm-Liouville problem with non-local 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 complex ...
