Abstract

CDE is a Reduce package devoted to differential-geometric computations on Differential Equations (DEs, for short). The package is included in the official Reduce sources in Sourceforge [37] and it is also distributed on the Geometry of Differential Equations web site http://gdeq.org (GDEQ for short). We start from an installation guide for Linux and Windows. Then we focus on con- crete usage recipes for computations in the geometry of differential equations: higher symmetries, conservation laws, Hamiltonian operators and their Schouten bracket, re- cursion operators. All programs discussed here are shipped together with this manual and can be found in the Reduce sources or at the GDEQ website. The mathematical theory on which computations are based can be found in refs. [12, 22].
