Flat Modules and Homological Dimensions,tive in ., then . ⊗. . → . ⊗. . is injective also. Projective modules are flat, but flat modules enjoy an important property not shared by projective modules: they are .. In particular, a module is flat if all f.g. submodules are flat. Over ℤ, the flat modules are just the torsion-free abelian group
