Spectral Properties of the Laplace Operator with Variable Dependent Boundary Conditions in a Disk

open access: yesAxioms
In this work, we study the spectral properties of the Laplace operator with variable dependent boundary conditions in a disk. The boundary conditions include periodic and antiperiodic boundary conditions as well as the generalized Samarskii–Ionkin-type ...

Oscillation theory for a pair of second order dynamic equations with a singular interface

open access: yesElectronic Journal of Differential Equations, 2008
In this paper we consider a pair of second order dynamic equations defined on the time scale $I = [a,c]cup [sigma(c),b]$. We impose matching interface conditions at the singular interface $c$.
