Consider a 4 current
J^\mu and a metric g then conservation laws will require \del_\mu J^\mu = 0
my lecturer gave me a brief problem and I think I'm missing some understanding of it
he writes
What I'm not understanding is, where he states, if we choose B to be the time slice between etc...
This doesn't make sense because to have Q(t1)-Q(t2) don't you need to integrate equation 4 over 2 times different times again? or at least evaluate at t1 and subtract by the value evaluated at t2?
