| Nov 20, 2016 at 13:07 | comment | added | Denis Nardin | @Riccardo Sorry, there were some leftover from the first draft (when I did not realize that we could restrict to finite spectra where the problem is easy). Now it should be better. I also added an explanation of why we can restrict to finite spectra (basically: every homology theory is determined by its restriction to finite spectra, so its operations are too). | |

Removed residues of the first draft; exanded explanation for the AHSS

| Nov 20, 2016 at 9:59 | comment | added | Riccardo | In the first part of your answer you claim that if $X$ is finite spectrum then all the homology operations comes from a map of spectra, don't you? Because just before you said that you ignore if all of the homology operations "comes from cohomology operations" but then it seems that you prove that all homology operations are of that form.I am "stressing" this point since in the lemma I am referring to $X$ is just any spectrum, not necessarily finite | |
