For ring spectra, a reference is Higher Algebra, 7.1.3.15, but it's probably simpler to prove by identifying connective $E_\infty$-ring spectra with models for a certain Lawvere theory, where you can just apply the corresponding statement for spaces. | |
| Jun 3, 2021 at 13:37 | comment | added | Tintin | Thank you very much, Denis. That indeed is a nice solution. One more thing, do you know a reference where I can read about the adjunction between groups/rings and spectra/ring spectra? The references I see only do the construction of $H$ and I am interested in reading in detail the adjoint map $1\to H\pi_0$, I don't see how to do it. Thanks in advance | |
