Generators of boosts and rotations. The Lorentz group can be thought of as a subgroup of the diffeomorphism group of R 4 and therefore its Lie algebra can be identified with vector fields on R 4.

Here, v is the parameter of the transformation, for a given boost it is a constant number, but in general can take a continuous range of values. In the setup used here, positive relative velocity v > 0 is CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The long established but infrequently discussed dependence of Lorentz boost generators on the presence and nature of interactions is reviewed in this tutorial note.

Using the generators given in Eq(2) it is straightforward to work out commutators of these generators, [M ;M ] = i(g M g M g M +g M ) De–ne M ij = ijkJ k; M oi = K i where J0 k scorrespond to the usual rotations and K i the Lorentz boost operators. We can solve for J i to get J i = 1 2 ijkM jk The commutator of J0 i sare, [J i;J j] = 1 2 2 " ikl" jmn[M kl;M

Thank you guys for the answer. I do wonder why the ##t=0## generator is prefered for the presentation of the Galilean and the Poincare algebra, it seems to hide some physical interpretation of the boost generator, and it is not much of a simplification in the math.

We may now collect the results into one transformation matrix: for simply for boost in x-direction . the same commutation relations as the generators of O(3). (Of course, you Lorentz transformation matrices, then so is the matrix Λ3 = Λ2 Λ1,. (Λ3)µ ν = (Λ2)µ .
