Une application est dite injective ou est une injection si pour tout y dans l'ensemble d'arrivée Y, il existe au plus un élément x dans l'ensemble de définition X tel que f(x) = ... 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. (Equivalently, x1 ≠ x2 implies f(x1) ≠ f(x2) in the equivalent contrapositive statement.)

WebbCardinality definitions. You may have noticed that in our examples of injections, there are always at least as many elements in as there are in .Similarly, surjections always map to smaller sets, and bijections map to sets of the same size. This insight lets us use functions to compare the sizes of sets in a way that applies to infinite sets as well as finite sets. Webb13 juni 2024 · be the canonical injection (defined by φ i ( x) = ( x, i) ). The disjoint union topology on X is defined as the finest topology on X for which all the canonical injections φ i are continuous (i.e.: it is the final topology on X induced by the canonical injections). Explicitly, the disjoint union topology can be described as follows.
