Stability of the basis property of eigenvalue systems of Sturm-Liouville operators with integral boundary condition

Electronic Journal of Differential Equations, 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.

Eigenfunction expansion for impulsive singular Hahn–Dirac system [PDF]

In this study, a singular impulsive Hahn–Dirac system is studied. A spectral function has been established for this type of system.

On the parity of the number of nodal domains for an eigenfunction of the Laplacian on tori

, 2015
In this note, we discuss a question posed by T. Hoffmann-Ostenhof (see [3]) concerning the parity of the number of nodal domains for a non-constant eigenfunction of the Laplacian on flat tori. We present two results.
