could someone give an indication about where the name comes from ? There seems to be no mathematician named "Tor". — MFH:Talk 12:56, 21 February 2006 (UTC)
- Torsion in abstract algebra; see torsion (abstract algebra) Charles Matthews 13:43, 21 February 2006 (UTC)
Note that there is Tor functors too. nikita 17:26, 13 June 2006 (UTC)
[edit] When is this true?
Tor(A,B) is the tensor product of the torsion subgroups of A and B respectively. --Raijinili (talk) 05:39, 10 August 2008 (UTC)
