A module E is called the injective hull of a module M, if E is an essential extension of M, and E is injective.Here, the base ring is a ring with unity, though possibly non-commutative. Examples. An injective module is its own injective hull. The injective hull of an integral domain is its field of fractions (Lam 1999).; The injective … En injektiv funktion är en funktion f, från mängden X till mängden Y, sådan att f:s definitionsmängd Df = X och f:s värdemängd Vf Y, det vill säga, Vf är en delmängd av Y. En alternativ definition av injektiv funktion, kan även uttryckas som: En funktion f är injektiv om, det för varje y i målmängden Y finns högst ett element x i definiti…

Assume f: A → B has a left inverse g: B → A, so that g ∘ f = i d . We want to show that f is injective, i.e. that for all x 1, x 2 ∈ A, if f ( x 1) = f ( x 2) then x 1 = x 2. Choose arbitrary x 1 and x 2 in A, and assume that f ( x 1) = f ( x 2). diseases of silkworm slideshare ppt

WebbWikipedia explains how left-inverse implies injectivity. Oct 17, 2024 at 6:46 1 @rb612 Yes! If f not injective, then applying the function loses information, because different things are mapped to the same thing. You can't undo that loss of information afterwards, meaning there can't be a g such that g ∘ f is the identity.
