what is the spanier-whitehead dual of the suspension spectrum of CP^infty?

@AaronMazel-Gee I found myself.

in the quiz, not like some kind of apiritual enlightenment lol

Apparently I'm not the only one. I'm ambivalent about being the most notorious MO eccentric…

@skd up to profinite completion, it's a shift of CP^∞. (this is a result of Ravenel; i'll try to remember the reference.) i don't know how dramatic that completion is, but i suspect fairly dramatic

whew sorry that was not the right thing to say at all. one moment

well, it wasn't that far off, but anyway see Theorem 1.11.(iii) in Ravenel's The Segal Conjecture for Cyclic Groups and Its Consequnces

this is a cooler paper than i remembered. possibly i didn't read beyond this exact result

thanks, eric. my first thought was what you initially suggested too, but it seems like the dual is huge

sw duals of infinite spectra are weird. they aren't nonzero very often, but when they are they're absurd

9.

Well, I don't know how that happened

So sorry about that

(I also didn't realize I could post here)

Anyway, the Kerodon project looks amazing!
