Webb21 jan. 2024 · Recall the definitions: an injective map is a map that does not map any two different elements to the same element. This is in general. For the specific case of linear maps, you can prove that it is equivalent to not mapping any non-zero element to 0, which in turn is equivalent to ker ( T) = { 0 }. Webbabsolutely pure and pure injective, and is thus injective by [30, Lemma 12.3.16]. For the converse, any injective is flat by Proposition 2.8, and injectivity implies pure injectivity by definition.

In mathematics, an injective function (also known as injection, or one-to-one function) is a function f that maps distinct elements of its domain to distinct elements; that is, f(x1) = f(x2) implies x1 = x2.
