Hi Francesco, I'm sorry for my long latency time.
Concerning a Lie algebra defined by the structure constants: keep in mind > this is a way often used in Physics, which is not very rigorous. Structure > constants define an equivalence class of bases in a Lie algebra. > > For example, consider a Lie algebra with two generators: *A, B*. If you > define *X = 2*A - 3*B, Y = A + B*, then *X *and *Y* are still generators, > but will have generally different structure constants. > Yes, that is clear to me. Maybe the documentation is too imprecise at this point. Unfortunately a "real" Lie-Algebra class makes (except in the semisimple case) no sense, because the classification of Lie-Algebras is really a non-trivial problem. You may have a look on the method GLV_Action(self, a): #Computes the Action of an Element of GL(V) on the Variety of Structure Constants Due to your other remarks, I will revise my code promptly.
