    Die Absicht des Verf. ist, vollständige Systeme von fundamentalen Lösungen für die wichtigsten partiellen Differentialgleichungen der mathematischen Physik zu finden. Die vorliegende Abhandlung, in der die Gleichungen \[ \begin{gathered} \frac{\partial v}{\partial r}=\frac{\partial ^2v}{\partial x^2},\quad \frac{\partial^2 u}{\partial t^2}= \frac{\partial^2 u}{\partial x^2}, \\ \frac{\partial v}{\partial t}=\frac{\partial ^2v}{\partial x^2} + \frac{\partial^2v}{\partial y^2}+\frac{\partial^2v}{\partial z^2},\quad \frac{\partial^2u}{\partial t^2}=\frac{\partial^2u}{\partial x^2}+ \frac{\partial^2u}{\partial y^2}+\frac{\partial^2u}{\partial z^2} \end{gathered} \] mit unstetigen Anfangsbedingungen betrachtet werden, bringt nur einige vorläufige Ergebnisse.
