    added pointer to today’s

    Though I haven’t actually absorbed this yet.

    I see they reference the paper by Hisham I added in #1.

    Thanks for the alert. I have fixed the formatting of 𝕆P 2\mathbb{O}P^2 in the entry.

    a natural map of the conjectured “bosonic M-theory” of Horowitz and Susskind in 26 + 1 down to M-theory in 10 + 1.

    So what’s the inverse image of twisted cohomotopy?

    What do you mean? Do you mean the kernel of the map from Cohomotopy to K-theory?

    I haven’t read what they’re saying closely enough, but since they were talking about a chain of reductions generating a map from bosonic M-theory to ordinary M-theory, aspects of the latter may appear as reductions of the former, e.g., the C-field may have its preimage in bosonic M-theory.

    I see a brief mention of the bosonic case appears in Hisham and Daniel’s recent arXiv:2001.07640 (p. 16). The octonionic Hopf fibration has to figure somewhere.

    By the way, Urs, you could pass on that there’s a typo on p. 15,

    in this case we get that degree 5 cohomotopy gives a contribution to cohomology in higher degree,

    should be degree 4.

    Thanks! Will do.
