    I have started an entry Majorana spinor with discussion of how the physicist’s concept going by that name is a real structure on a complex spin representation.

    Initially I had wanted to just follow the note by Figueroa-O’Farrill, but either I am missing something or else there is a gap in the argument there.

    So in particular at the moment I have just one direction “Majorana structure is real structure”, not the converse.

    (And why is it that the proposition number cross referencing is again broken?)

    I have expanded a good bit further at Majorana spinor.

    Have added a section Examples – In dimensions 11, 10 and 9 with a bunch of relations between Majorana spinors in these dimensions that govern KK-compactification and T-duality between the corresponding supergravity theories.

    added a subsection Examples – Properties of spinors in 11d (here)

    with a bunch of facts.

    (Some of these are duplicated at geometry of physics – fundamental super p-branes, but it’s good to have them here, too.)
