Webb17 aug. 2024 · Definition (Injective, One-to-One Linear Transformation). A linear transformation is said to be injective or one-to-one if provided that for all u1 and u1 in U, whenever T(u1) = T(u2), then we have u1 = u2. Proof. ( ): If T is injective, then the nullity is zero. Suppose that T is injective. Webb4 juli 2024 · In some circumstances, an injective (one-to-one) map is automatically surjective (onto). For example, Set theory An injective map between two finite sets with the same cardinality is surjective. Linear algebra An injective linear map between two finite dimensional vector spaces of the same dimension is surjective. General topology
WebbAn injection, or one-to-one function, is a function for which no two distinct inputs produce the same output. A surjection, or onto function, is a function for which every element in the codomain has at least one corresponding input in the domain which produces that output. A function that is both injective and surjective is called bijective.
