    I see there’s a conference coming up Generalized Cohomology and Physics. EDIT: Link corrected as per #3 (and #5).

    By the way, I came across your essay, Urs, The use of nonabelian differential cohomology. Perhaps worth an indication of what has come to be seen post-2012?

    The link in your #1 is probably meant to be indico.ictp.it/event/9639.

    Regarding #2: The latest exposition of non-abelian differential cohomology and physics we have is the Introduction to The character map in (twisted differential) non-abelian cohomology.

    Yes, sorry, that link.

    Re #2, I just meant you might consider adding a mention on that page to a later exposition, as in #3. I was just looking about to see how commonly the physics-cohomology connection is made, and was sent to your 2012 essay.

    I have yet to see any trace of any philosopher of physics writing on cohomology.

    The link is still broken!

    It’s almost as though I don’t want people to find it.
