WebGenerally speaking, a homomorphism between two algebraic objects A,B A,B is a function f \colon A \to B f: A → B which preserves the algebraic structure on A A and B. B. That is, if elements in A A satisfy some algebraic equation involving addition or multiplication, their images in B B satisfy the same algebraic equation. WebIn ring theory, a branch of abstract algebra, a ring homomorphism is a structure-preserving function between two rings.More explicitly, if R and S are rings, then a ring homomorphism is a function f : R → S such that f is:. addition preserving: (+) = + for all a and b in R,multiplication preserving: = () for all a and b in R,and unit (multiplicative identity) …

Homeomorphism (graph theory) - Wikipedia
WebEdit. View history. Tools. In algebra, a homomorphism is a structure-preserving map between two algebraic structures of the same type (such as two groups, two rings, or two vector spaces ). The word homomorphism comes from the Ancient Greek language: ὁμός ( homos) meaning "same" and μορφή ( morphe) meaning "form" or "shape". In the mathematical field of graph theory, a graph homomorphism is a mapping between two graphs that respects their structure. More concretely, it is a function between the vertex sets of two graphs that maps adjacent vertices to adjacent vertices. Homomorphisms generalize various notions of graph colorings and allow the e… • Serge Lang: Algebra. (= Graduate Texts in Mathematics. 211). 3., überarb. Auflage.
