Homework Statement
Find the 3D representation of what I think are the commutators [T_a,T_b] for the SU(2) group
Homework 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?
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?
