Detection of stable homotopy by Ktheory spectra
@BenWieland Sorry, so in saying that char. 0 fields and transcendental char. p fields detect everything, you're saying that they detect elements of all heights? Or are you saying rather that the detect the entire image of J?

Detection of stable homotopy by Ktheory spectra
Wow Ben, thank you so much for your answer! That's really helpful. So, it would seem then that from a chromatic point of view, algebraic Ktheory is (at least morally) sort of stuck at height 1?

Multiplicative Structures on Moore Spectra
For what it's worth, it seems like what you're getting at is this fundamental difficulty we have in spectra of talking about "modding out by ideals," since you're only looking at localization versus taking quotients.

forcing and set theory
It might help to check out the FAQ and spend a little more time writing your question. Explain why you're interested, what's the motivation? Describe previous work on the topic, etc.

Thom Spectra and HopfGalois Extensions of Ring Spectra
I should also mention that that convergence I mention definitely holds for a LOT of interesting Thom spectra: $MU$, $MSO$, $MSU$, $X(n)$, Baker and Richter's $M\xi$. And the alternate situation (being an extension of the 2adic sphere spectrum) holds for $MO$.

Ah thanks @JustinNoel I had seen that word (primitives) used in some places. Perhaps it will be less confusing if I start using that rather than cofixed points.
