| Dec 2, 2010 at 14:22 | comment | added | Graham Leuschke | Certainly not faithful in general. Lot of examples when $A$ is local, but $f$ is not a local homomorphism. For example, it could be the inclusion of a domain into its quotient field. Then all the torsion stuff will die, definitely non-faithful. | |
