Stability of the basis property of eigenvalue systems of Sturm-Liouville operators with integral boundary condition
Autor: Nurlan S. Imanbaev
Publikováno v: Electronic Journal of Differential Equations, Vol 2016, Iss 87,, Pp 1-8 (2016)
We study a question on stability and instability of the basis property of a system of eigenfunctions of the Sturm - Liouville operator, with an integral perturbation of anti-periodic type on the boundary conditions.

On a Problem that Does not Have Basis Property of Root Vectors, Associated with a Perturbed Regular Operator of Multiple Differentiation
Autor: Nurlan S. Imanbaev
Publikováno v: Journal of Siberian Federal University. Mathematics & Physics. :568-573
A spectral problem for a multiple differentiation operator with integral perturbation of boundary value conditions which are regular but not strongly regular is considered in the paper. The feature of the problem is the absence of the basis property

A regular differential operator with perturbed boundary condition
Autor: Makhmud A. Sadybekov, Nurlan S. Imanbaev
Publikováno v: Mathematical Notes. 101:878-887
The operator ℒ0 generated by a linear ordinary differential expression of nth order and regular boundary conditions of general form is considered on a closed interval. The characteristic determinant of the spectral problem for the operator ℒ1, wh

Eigenvalue Problem for Differential Cauchy–Riemann Operator with Nonlocal Boundary Conditions
Autor: Nurlan S. Imanbaev
Publikováno v: Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, Vol 1(34), Pp 25-36 (2014)
We consider the reduced spectral problem for the Cauchy–Riemann operator with nonlocal boundary conditions to Fredholm linear integral equation of the second kind with a continuous kernel. The corresponding Fredholm determinant is defined for all s

Regular Sturm-Liouville Operators with Integral Perturbation of Boundary Condition
Autor: Nurlan S. Imanbaev, Makhmud A. Sadybekov
Publikováno v: Springer Proceedings in Mathematics & Statistics ISBN: 9783319670522
We are studying the issue of stability and instability of the basis property of the system of eigenfunctions and associated functions of the Sturm-Liouville operator with an integral perturbation of one boundary condition. This paper is devoted to a
