Hopf-algebras in associative ring spectra
Actually this answer is rife with mistakes and misunderstandings. I'll try to update it soon... |

Thom Spectra and Hopf-Galois Extensions of Ring Spectra
I should perhaps also add that in certain nice cases I have been able to work this out (the write-ups are on my website). But that relies on the collapse of a certain Kunneth spectral sequence which seems unlikely in general. It would be nice to have more general conditions. |

Hopf-algebras in associative ring spectra
Point taken. It's true that I was just sort of generalizing willy nilly from commutative algebra which, as you say, doesn't make any sense. |

Associative Ring Spectra and Derived Completion
Jacob have you (or anyone else) written down somewhere a proof that it's true under the conditions (on $\pi_0$ and $\pi_1$) that Carlsson gives? |

Fair enough. I'll rephrase the question. |

Cohomology of Formal Groups
Yeah totally! I suppose I should also mention that I worked with this structure in a preprint of mine: math.jhu.edu/~beardsle/lubinTateComplex.pdf |

What is an infinite prime in algebraic topology?
I would say the people who could really speak to this are Andrew Salch and Jack Morava, neither of whom are, unfortunately, on MathOverflow. |

What is an infinite prime in algebraic topology?
I haven't heard of anything like this. I suppose in some sense one could try to think of "valuations" as corresponding to Bousfield localizations, or at least, localizations that behave like completion (e.g. localization at HF_p or Morava K-theory). There may be a fruitful analogy to be made here between certain Bousfield localizations and a notion of "valuations" on the sphere spectrum. I guess in some sense topology doesn't SEE the Archimedean place. |

Category of modules over commutative monoid in symmetric monoidal category
This sort of stuff is shown in a lot of places that I know of for topological categories, and these things follow as degenerate cases of that, but that's probably overkill. |

Higher coherent multiplicative structures on S-algebras
I see. Ah, that's frustrating. I mean, yeah, I'm interested entirely in $E_2$ and above, but I guess I was hoping this had been worked out. Thanks! |
