tex2html_wrap124 so a lorentz transformation can be thought of as a rotation in 4 dimensions.

infinitesimal transformation definition:

tex2html_wrap125 .

This has been worked out for 3-d rotations.

tex2html_wrap126 . With this, you can express tex2html_wrap127 where tex2html_wrap128 is normalized. commutation relations: tex2html_wrap129 . In the lorentz case, tex2html_wrap130 where tex2html_wrap131 so tex2html_wrap132 . tex2html_wrap133 . tex2html_wrap134
