| Sep 22, 2017 at 5:57 | comment | added | Denis Nardin | @54321user It's just an easy consequence of the Dold-Kan correspondence. In particular, the homotopy groups of a simplicial abelian group are the homology groups of the associated complex (see C. Weibel, An introduction to homological algebra exercise 8.4.4). | |
