Talk:Bockstein homomorphism

Mod 2 Bockstein
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 → Z → Z → Z/pZ → 0

where the first map is multiplication by p, to the sequence
 * 0 → Z/pZ → Z/p2Z → Z/pZ → 0. —Preceding unsigned comment added by 71.37.53.15 (talk) 21:43, 1 May 2011 (UTC)
