Sign-Changing Points of Solutions of Homogeneous Sturm-Liouville Equations with Measure-Valued Coefficients

Ahmed Ghatasheh, Rudi Weikard

In this paper we investigate sign-changing points of nontrivial real-valued solutions of homogeneous Sturm-Liouville differential equations of the form $- d (d u / d α) + u d β = 0$ , where $dα…

Spectral Theory for Systems of Ordinary Differential Equations with Distributional Coefficients

Ahmed Ghatasheh, Rudi Weikard

We study the spectral theory for the first-order system $J u^{'} + q u = w f$ of differential equations on the real interval $(a, b)$ when $J$ is a constant, invertible skew-Hermitian matrix…
