I am reading Bousfield's paper entitled "The localization of spectra with respect to homology" (MSN). In that paper, Corollary 6.13 states that, if a ring spectrum $E$ has countable homotopy and satisfies some vanishing conditions in the associated Adams spectral sequence, then the localization is equivalent to nilpotent completion.

So, my question is the following:

What are the ring spectra $E$ (I need an updated list) satisfying the above conditions?

  • $\begingroup$ @VictoriaM, thanks! I have edited in a link to the abstract (which I think is generally to be preferred to the PDF, especially since it's freely available). $\endgroup$

  • $\begingroup$ Should your hypothesis "if a ring spectrum $E$ with countable homotopy and satisfies …" be "if a ring spectrum $E$ has countable homotopy and satisfies …"? $\endgroup$

  • $\begingroup$ Morava $E$ theories satisfy the condition I think. That's why they are smashing! $\endgroup$
