Abstract |
|
The functor Tor is related to some classes of Cλ groups, notably the IT groups, and when λ = Ω the CΩ groups of balanced projective dimensions 1. Separate necessary and sufficient conditions are given for Tor(G,H) to be a d.s.c. group when G and H are Cλ groups. Some generalizations of the fact that balanced subgroups of G and H determine balanced subgroups of Tor(G,H) are presented. |
