Hi! I am looking for software (preferably a Mathematica package) to perform the following calculations for a given exterior differential system: - check involutivity of a given vector field system - calculate Cauchy characteristic vectors - check whether a linear subspace is an integral element of the system - calculate the Cartan characters for a given integral flag I have found some packages to calculate with differential forms (implementing wedge products and a exterior differential operator) but none of these packages could perform the tasks mentioned above. kind regards, pieter eendebak
