7.7.2.0. variablesSorted
Procedure from library central.lib (see central_lib).
- Usage:
- variablesSorted();
- Return:
- ideal, generated by sorted algebra variables
- Purpose:
- computes the set of algebra variables sorted so that
Cartan variables go first
- Note:
- This is a heuristics for the computation of the center:
it is better to compute centralizers of Cartan variables first since in this
case we can omit solving the system of equations.
Example:
