Izomorfismus je zobrazení mezi dvěma matematickými strukturami, které je vzájemně jednoznačné (bijektivní) a zachovává všechny vlastnosti touto strukturou definované. Jinými slovy, každému prvku první struktury odpovídá právě jeden prvek struktury druhé a toto přiřazení zachovává vztahy k ostatním prvkům.. O izomorfismech je možno mluvit mezi množinami. In mathematics, an isomorphism is a structure-preserving mapping between two structures of the same type that can be reversed by an inverse mapping.Two mathematical structures are isomorphic if an isomorphism exists between them. The word isomorphism is derived from the Ancient Greek: ἴσος isos equal, and μορφή morphe form or shape.. The interest in isomorphisms lies in the.

Definition 2.2 Graph Epimorphism. An epimorphism (EPI) from G to G ′ is a surjective function f: V → V ′ such that • for all u, v ∈ V, if (u, v) ∈ A, then (f (u), f (v)) ∈ A ′ (graph homomorphism), and, • for all (u ′, v ′) ∈ A ′, there exists (u, v) ∈ A such that f (u) = u ′ and f (v) = v ′ (surjectivity on arcs). If f is bijective, then f is a graph isomorphism An epimorphism of commutative rings is the same thing as a monomorphism of affine schemes. Monomorphisms are not only embeddings, e.g., any localization is an epimorphism and the corresponding morphism of schemes is not a locally closed embedding Special types of homomorphisms have their own names. A one-to-one homomorphism from G to H is called a monomorphism, and a homomorphism that is onto, or covers every element of H, is called an epimorphism. An especially important homomorphism is an isomorphism, in which the homomorphism from G to H is both one-to-one and onto. In this last case, G and H are essentially the same system.

surjective morphism of schemes or epimorphism of sheaves? Ask Question Asked 9 years, 1 month ago. Active 8 years, 11 months ago. Viewed 2k times 8. 7 $\begingroup$ I have a technical question coming from reading Toen's master course on stacks. If we view schemes as locally ringed spaces then there we could define a morphism to be surjective if. It comes from the fact that the prefix epi is Greek for upon, over, or at. The prefix is also used in, epidemic, epidermis, or epicenter to indicate these meanings. Thus an onto homomorphism is said to be an epimorphism, i.e. a morphism which maps over/upon/onto the range of the function Dalam teori kategori, epimorfisma (juga disebut morfisme epik atau, bahasa sehari-hari, epi) adalah morfisma f:X→Y sehingga adalah pembatalan-kanan dalam arti bahwa, untuk semua objek Z dan semua morfisme g 1, g 2: Y → Z, ∘ = ∘ =.

Informally, we said that a category is set-based, if its objects are sets with additional structures (e.g., semigroups, groups, vector spaces.
