In this paper, we consider some boundary value problems generated by third-order formally
symmetric (self-adjoint) regular differential expression and separated, real-coupled and …

The aim of this study is to generalize some important spectral properties of classical periodic
Sturm–Liouville problems to two‐linked periodic problems with additional transmission …

This work is aimed at studying some comparison and oscillation properties of boundary
value problems (BVP's) of a new type, which differ from classical problems in that they are …

This work studies the singular Hahn-Dirac system given by Here 𝜇 is a complex spectral
parameter, p (.) and r (.) are real-valued continuous functions at 𝜔0, defined on [𝜔0,∞) and …

It is well-know that the Sturm-Liouville theory justifies the" separation of variables" n method
for voluminous partial differential equation problems. For Sturm-Liouville problems the …

In this paper, we propose a new type of boundary value problems for 2-interval Sturm-
Liouville equations which differs from the classical periodic Sturm-Liouville problems in that …

In this paper a Sturm–Liouville equation together with eigenparameter-dependent boundary-
transmission conditions are considered on two disjoint intervals. We construct the resolvent …

In this paper we introduce to consideration a new type boundary value problems consisting
of an “Sturm-Liouville” equation on two disjoint intervals as− p (x) y′′+ q (x) y+ By| x= µy …

A class of inverse Sturm–Liouville problems of Atkinson type with eigenparameter-
dependent boundary conditions is investigated. By using the matrix representations of the …

For the generalized Sturm–Liouville problem (GSLP), a new formulation is undertaken to
reduce the number of unknowns from two to one in the target equation for the determination …
