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

open access: yesДоповiдi 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 ...

Fractional Sturm-Liouville operators on compact star graphs

open access: yesDemonstratio Mathematica
In this article, we examine two problems: a fractional Sturm-Liouville boundary value problem on a compact star graph and a fractional Sturm-Liouville transmission problem on a compact metric graph, where the orders αi{\alpha }_{i} of the fractional ...

Eigenvalues of Sturm-Liouville operators and prime numbers

open access: yesElectronic Journal of Differential Equations, 2017
We show that there is no function $q(x)\in L_2(0,1)$ which is the potential of a Sturm-Liouville problem with Dirichlet boundary condition whose spectrum is a set depending nonlinearly on the set of prime numbers as suggested by Mingarelli [7].
