We develop different software packages:
The Maple library jets was originally meant to be an extension of the package desolv, where functions for computating generalized symmetries were added. Now it is an independent package, whose capabilities are beyond computating symmetries. Further informations can be found on the webpage of Mohamed Barakat.
Involutive and Janet
The Janet-algorithm produces a normal form for systems of linear partial differential equations respectively for systems of polynomial equations. Implementations are now available for Maple. The packages Janet and Involutive offer various other functions for concrete applications.
One of these applications ist for example the control theory.
The Thomas-algorithm constructs a decomposition of systems of algebric or differential equations and inequations into simple systems.
The CoW package for Maple implements the computation of the comprehensive weight enumerator of a linear code.
The homalg project is meant as a continiously growing, source open book in several volumes about homological and homotopical algebra. homalg tries to translate as much homological algebra into a language understandable for a computer as possible. But homalg also should be readable in wide parts for mathematicans without programming experience. GAP4 was choosen as language for homalg for a huge amount of reasons.
An application of homalg is the package conley. This package calculates connection and stochastic matrices of Morse decompositions of a dynamical system.
The Maple package PSL is an implementation of methods for recognizing groups of type L_2 as an epimorphic image of a finite representable group.
Quillen Suslin is a Maple package, which implements algorithms for calculating bases of free moduls over polynomial rings.
By using the package CARAT, it is possible to construct and classificate cristallographycal space groups up to dimension 6. Further informations can be found at the CARAT homepage. The newest version is available for download there.
OreModules is a Maple implementation of algorithms which compute parametrizations, extension modules (ext), resolutions and other algebraic objects for linear systems of differential equations, time-delay systems, etc. The package OreModules, based on an original program by F. Chyzak and A. Quadrat, is maintained and further developed by A. Quadrat and D. Robertz.
