Spectral properties of a fourth-order eigenvalue problem with spectral parameter in the boundary conditions

Autor: Ziyatkhan S. Aliyev, Faiq M. Namazov

Publikováno v: Electronic Journal of Differential Equations, Vol 2017, Iss 307,, Pp 1-11 (2017)

In this article we consider eigenvalue problems for fourth-order ordinary differential equation with spectral parameter in boundary conditions. We study the location of eigenvalues on the real axis, find the multiplicities of eigenvalues, investig
