I know the representations of Lorentz generators M[tex]\mu\nu[/tex] as 4X4 matrices.
This matrices satisfy the commutation relation(Lie algebra of O(3,1))
However I think these 4X4 matrix representations are not unique.
Is there any other representations satisfying the commutation relation? 2X2 matrix or
another?
