|
| 43. | More generally, an abelian group is injective if and only if it is divisible.
|
| 44. | One can use injective hulls to define a minimal injective resolution ( see below ).

| 45. | One can use injective hulls to define a minimal injective resolution ( see below ).
|
| 46. | It is not, however, injective.
|
| 47. | Moreover, morphisms of complexes extend uniquely to a morphism of two given injective resolutions.
|
| 48. | This action is faithful, which is equivalent to curry ( T ) being injective.
|
| 49. | More strongly, every non-locally-injective cellular automaton has an orphan pattern.
|
| 50. | However, every image of a perfect space under an injective continuous map is perfect.
