I try to understand where the intrinsic spin symmetry of spacetime (ISSS) is established. I read articles but still do not understand how to put together all the information to make a clear picture of where ISSS comes from.(adsbygoogle = window.adsbygoogle || []).push({});

Minkowski space - Lorentz group O(1,3) - Covering SO(1,3) with SL(2)c - Homomorphism of SL(2)c and SO(1,3), Lie Algebra so(1,3), construction of representations of sl(2)c and SO(1,3), Poincaré group and the classification of the representations, relationship to Noether theorem.

Any references and ⁄ or that would give me a explanations of why all these steps and what they each mean, and give me physical interpretations⁄reasons of all these mathematical structures would be more that wellcome :-)

Thank you very much, AlephClo
