   So what’s the inverse image of twisted cohomotopy?

   Format: MarkdownItexI 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.
