Abstract

In this study, a formula for regularized sums of eigenvalues and nodal
points of eigenfunctions for a discontinuous Sturm-Liouville problem with a
constant retarded argument. Contrary to standart problems the spectral
parameter appears not only in the differential equation, but also in one of the
boundary conditions. Thus, we see whether the nodal points of eigenfunctions
and the trace change or not.

Abstract

Biz bu
çalışmada sabit geciken argümanlı süreksiz bir Sturm-Liouville probleminin
özdeğerleri için bir iz formülü ve özfonksiyonları için düğüm noktaları elde
ettik. Standart problemlerin aksine spektral parametre sadece diferansiyel denklemde
değil ayrıca sınır koşullarının birinde de yer alır. Böylece bu durumun
özfonksiyonların düğüm noktalarını ve izini değiştirip değiştirmediğini görmüş
oluyoruz.
