Order isomorphism

WebJan 3, 2024 · A basic problem in the theory of partially ordered vector spaces is to characterise those cones on which every order-isomorphism is linear. We show that this is the case for every Archimedean cone that equals the inf-sup hull of the sum of its engaged extreme rays. This condition is milder than existing ones and is satisfied by, for example ... WebJun 11, 2024 · A function or mapping between two groups is a homomorphism if it is operation-preserving, and an isomorphism is a one-to-one and onto homomorphism. To show a mapping φ:G→H is one-to-one, the usual procedure is to assume that g 1 and g 2 are elements of G such that φ (g 1) = φ (g 2 ), and then show that g 1 = g 2.

Glossary [ edit] 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. WebAug 30, 2024 · The concept of order isomorphismwas first introduced by Georg Cantor. Linguistic Note The word isomorphismderives from the Greek morphe(μορφή) meaning formor structure, with the prefix iso-meaning equal. Thus isomorphismmeans equal structure.
