The product of any two rotation matrices is a rotation matrix, i.e., successive applica- tion of two rotations is itself a rotation. This is in contrast to boosts, which do

SU(2) and the Lorenz group. Now it’s time to study the Lorenz group and to discover that there is a correspondance between SU(2) and the Lorenz group. Pure ‘boost’ Lorenz transformations are those connecting two inertial frames, moving with relative speed v. If the relative motion is along the x-axis this could be put into matrix form as

While the rotation generators are Hermitian, the boost generators are anti-Hermitian JJ K K††==−, while . (1.11) ii Physics of the Lorentz Group 1-2 The Lorentz group is a collection of linear transformations of space-time coordinates x ! x0 = x which leaves the proper time ˝2 = (xo)2 (!x)2 = x x g = x 2 invariant. This requires the transformation matrix to satisfy the pseudo-orthogonality relation, g = g 1.1 Generators It is useful to investigate the group structure by studying their in–nitesmal elements near the identity, the generators. Lorentz Invariance in Physics > s.a.

As mentioned here, the commutator of two boost generators is a rotation generator. The “special Lorentz transformations”, which are those having a determinant equal to 1, include boosts, rotations, and compositions of these, and do form a group.
