Existence of solutions for a two-point boundary-value problem of a fourth-order Sturm-Liouville type

open access: yesElectronic Journal of Differential Equations, 2012
In this work, we establish the existence of two intervals for a parameter $lambda$ for which a two-point boundary-value problem of fourth-order Sturm-Liouville type admits three weak solutions whose norms are uniformly bounded with respect to $lambda$.

Spectrum and resolvent of multi-channel systems with internal energies and common boundary conditions

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
In the article the spectrum and resolvent of the so-called multichannel systems with nonzero internal energies were investigated. The spectrum and resolvent of multichannel Sturm-Liouville systems with non-zero internal energies mi2 and general boundary
