added pointer to today’s

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

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