Die Struktur der Extremallösungen von linearen Differentialgleichungen $n$-ter Ordnung

Abstract

The structure of extremal solutions of linear ordinary differential equations of order $n$ on an interval $[t_0,\eta (t_0)]$ is shown, where $\eta (t_0)$ is the first conjugate point of $t_0$. It is also shown by it, how this structure depends on the number of linearly independent extremal solution.
