    for the generalization of the theorem to (multiplicative) generalized cohomology theories.

    I have polished up the section “Statement”,

    and then I subdivided it into

    1. “In ordinary cohomology”

    2. “In generalized cohomology”

    and added re-statement of everything in the generalized version.

    (It’s verabtim the same statement, up to the evident substitutions, but it’s maybe good to have it spelled out again, anyways.)

    I have started writing out an example “Complex-oriented cohomology of the twistor fibration” (here). But it’s still lacking a punchline…
