Sorry, but could you clarify what you mean? For instance, what I'm saying is that su(2), for example, has a basis consisting of 3 elements, say u1, u2 and u3, and we know that [u1,u2] = 2(u3). But, for su(n) which has a basis of n^2 - n elements, I can't find an algorithm or anything saying that [u_i, u_j ] = f u_k for some constant f. -- You received this message because you are subscribed to the Google Groups "sympy" group.
