    I added four more references at twisted spin^c structure (aka “Freed-Witten anomaly cancellation”) after A clean formulation and review is provided in….

    Changed page name (from “twisted spin^c structure” to “twisted spinᶜ structure”) for better looks, following discussion here. Also changed “spin^c” to “spinᶜ” in related concepts. (Links will be checked.)

    Edit: Is there a reason for !redirects twisted spin^c structure being in there trice?

    These are articfacts and should be deleted. I think one reason for such duplicate redirects are page renamings:

    Namely the software is trying to be helpful in that when a page is renamed, it automatically inserts the old name page name as a redirect at the top of the source code. But this is easily missed (not the least because we traditionally list redirects at the end of the source code, instead).

    In any case, when you spot duplicate redirects, please delete them.

    (The one case to beware of are page names including hyphens: Several kinds of hyphens are visually indistinguishable, or essentially so, but have different character codings. This means that redirects with variants of hyphen-coding are both necessary while they may superficially look like duplicates.)

  1. Thanks for the explanation! I’ve deleted these artifacts and it was now added to the edit I had done a few minutes ago.
