Participant : Evelyne Hubert [ contact person ] .

The Maple package *diffalg* is a collection of routines to handle
systems of polynomial differential equations and inequations. The
functionalities include differential elimination, expansion of the
solutions into formal power series and analysis of singular solutions.
The underlying theory and terminology belongs to differential algebra.

Collaborators: François Boulier et François Lemaire from Univerity of Lille.
