Approaches for investigating nonlinear differential equations (DEs) are described and the status of corresponding programs is reported. Investigations include the determination of infinitesimal symmetries of single ODEs/PDEs or -systems, and for ODEs the determination of first integrals, of...

In relativ kurzer Zeit haben Open Source-Projekte als selbst organisierte, informale (Arbeits-)Netzwerke freiwillig Arbeitender, die durch eine rechtlich spezifische Lizenz ein „oeffentliches Gut“ erstellen, neben kommerzieller Software eine hohe Bedeutung erlangt. In dieser Arbeit wird die...
