Weinberg gives relations of SO(3)

[QUOTE="kent davidge, post: 6060949, member: 563342"] (Weinberg QFT, Vol 1, page 68) He considers Mass-Positive-Definite, in which case the Little Group is SO(3). He then gives the relations [ATTACH=full]231027[/ATTACH] Is it difficult to derive these relations? I'm asking this mainly because I haven't seen them anywhere other than in Weinberg's book. Also, I'm finding them difficult to follow, as on one side of the equations the ##J## have two indices whereas on the other side they have only one index. [/QUOTE]
