They all follow from the representation theory of Spin(4). In particular, they are needed to define the Dirac operator. | |
| Dec 6, 2014 at 10:30 | comment | added | Anton Fetisov | Take a look also at mathoverflow.net/questions/122748/what-is-a-spinor-structure and mathoverflow.net/questions/66681/… It doesn't make much sense to me to define a spin structure on a single vector space, like in your second definition. We should really consider vector bundles. | |
