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. -- You received this message because you are subscribed to the Google Groups "sympy" group.
