natural homomorphism
|
(Definition)
|
|
|
The natural homomorphism $R \rightarrow R/I$ where $R$ is a ring and $I$ an ideal of $R$ is the map $\alpha \mapsto \alpha + I$ Coset operations, e.g $(\alpha + \beta) + I = (\alpha + I) + (\beta + I)$ guarantee this will be a homomorphism. Natural
homomorphisms for groups can be defined similarly.
