Mod 2 Bockstein

edit

Why does the article say "ββ = 0 if p>2?" It is true for p=2.

To see why (works for any p>1), examine the map from the short exact sequence

0 → ZZZ/pZ → 0

where the first map is multiplication by p, to the sequence

0 → Z/pZZ/p2ZZ/pZ → 0. —Preceding unsigned comment added by 71.37.53.15 (talk) 21:43, 1 May 2011 (UTC)Reply

This page should have some examples of Bockstein maps included. Here's some references from stackexchange which are informative:
