On a generalized class of boundary-value problems with delayed argument
Erdoğan Şen
In this work, spectrum and asymptotics of eigenfunctions of a generalized class of boundary value problems with a delay are obtained.
Spectrum, trace and oscillation of a Sturm-Liouville type retarded differential operator with interface conditions
Erdoğan Şen
In this study, a formula for regularized sums of eigenvalues of a Sturm-Liouville problem with retarded argument at the point of discontinuity is obtained. Moreover, oscillation pr…
Asymptotic expressions of eigenvalues and eigenfunctions of a discontinuous boundary value problem with retarded argument which contains a spectral parameter in the boundary conditon
Erdoğan Şen
The aim of this study is to find asymptotic expressions of eigenvalues and eigenfunctions of a discontinuous boundary-value problem with retarded argument which contains a spectral…
Asymptotic properties of eigenvalues and eigenfunctions of a Sturm-Liouville problem with discontinuous weight function

Asymptotic behaviour of a differential operator with a finite number of transmission conditions
Erdoğan Şen, Oktay Mukhtarov
In this paper following the same methods in [M. Kadakal, O. Sh. Mukhtarov, Sturm-Liouville problems with discontinuities at two points, Comput. Math. Appl., 54 (2007) 1367-1379] we…
