meaning of SO(4) -- SU(2)xSU(2)
Hi,
I was doing an exercise in my QFT book asking me to show that the Lorentz Group SO(4) is isomorphic to SU(2)*SU(2) but not explaining why. I was wondering, and asking myself that maybe it has some "deep" meaning, about the relation between the spin and the relativity. Am I totally wrong?
