- How to derive the commutator of L and K according to the Lorentz commutation relations.
- Relevant Equations
- see below
Li=1/2*∈ijkJjk, Ki=J0i,where J satisfy the Lorentz commutation relation.
[Li,Lj]=i/4*∈iab∈jcd(gbcJad-gacJbd-gbdJac+gadJbc)
How can I obtain
[Li,Lj]=i∈ijkLk
from it?

How can I obtain
[Li,Lj]=i∈ijkLk
from it?
