1. The problem statement, all variables and given/known data Find the 3D representation of what I think are the commutators [T_a,T_b] for the SU(2) group 2. Relevant equations I think the generators(X_i) in SU(2) group are the 3 Pauli matrices, which are 2X2 matrices... I assume I need to find the matrices for these generators as 3x3? 3. The attempt at a solution I think the equation exp^(i*alpha_i*X_i) determines what the elements of the group are... [T_a,T_b)=T_a*T_b - T_b*T_a is the commutator Since there are 3 generators, does that also mean there should be three matrices in 3X3 representation? Do I sound confused????
