Description

A package for the computation of invariants and symmetries of evolution equations and lattices is presented. The Integrability package allows one to automatically compute invariants and symmetries. Applied to systems with parameters, it can be used to determine the conditions on these parameters so that a sequence of invariants or symmetries will exist, hence indicating integrability.
