Operator-pencil treatment of multi-interval Sturm-Liouville equation with boundary-transmission conditions

Қарағанды университетінің хабаршысы. Математика сериясы
This paper is devoted to a new type of boundary-value problems for Sturm-Liouville equations defined on three disjoint intervals (−π,−π+d),(−π+d,π−d) and (π−d,π) together with eigenparameter dependent boundary conditions and with additional transmission

Numerical study of the Sturm-Liouville problem

Iranian Journal of Numerical Analysis and Optimization
Summary: The article discusses the general Sturm-Liouville problem. To solve it numerically, a new algorithm is proposed, which is based on the variational principle and does not use saturation. The problem of constructing numerical methods for solving eigenvalue problems can be divided into two stages. First, we need to reduce the infinite-dimensional

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

, 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.

Inequalities and eigenvalues of Sturm-Liouville problems near a singular boundary

Journal of Inequalities and Applications, 2001
We study the behavior of eigenvalues of Sturm-Liouville problems (SLP) when an endpoint of the underlying interval approaches a singularity.

Multi-interval Sturm–Liouville boundary-value problems with distributional potentials

Доповiдi Нацiональної академiї наук України
We study the multi-interval boundary-value Sturm–Liouville problems with distributional potentials. For the corresponding symmetric operators boundary triplets are found and the constructive descriptions of all self-adjoint, maximal dissipative and ...
