Computation of Trace and Nodal Points of Eigenfunctions for a Sturm-Liouville Problem with Retarded Argument
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 3
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.

Eigenvalues of diffusion operators and Prime numbers
In this paper, the relationship between the positive eigenvalues of diffusion operators and prime numbers is investigated. We also propose a Sturm-Liouville problem with Coulomb singularity that shows eigenvalues the dis...
