WebAug 1, 2024 · An isomorphism is a 'structure-preserving bijection', but there are many different structures that it might preserve. One usually studies homo- and isomorphisms in a given context. In order theory, one studies order morphisms; in group theory, morphisms that preserve group structure. WebJul 12, 2024 · Two graphs G1 = (V1, E1) and G2 = (V2, E2) are isomorphic if there is a bijection (a one-to-one, onto map) φ from V1 to V2 such that {v, w} ∈ E1 ⇔ {φ(v), φ(w)} ∈ E2. In this case, we call φ an isomorphism from G1 to G2. Notation

WebSep 17, 2024 · A linear map T is called an isomorphism if the following two conditions are satisfied. T is one to one. That is, if T(→x) = T(→y), then →x = →y. T is onto.
