Noun
homomorphism (plural homomorphisms)
- (algebra) A structure-preserving map between two algebraic structures of the same type, such as group, ring, or vector spaces.
- A field homomorphism is a map from one field to another one which is additive, multiplicative, zero-preserving, and unit-preserving.

- This motivates a generalization, and exponential homomorphisms are now defined, in an algebraic fashion, from certain free products to formal power series rings with non-commutative indeterminates.

- A homomorphism of presheaves h : A \rightarrow B is a collection of homomorphisms h_U : A(U) \rightarrow B(U) commuting with restrictions.

- Definition 1.15. Let G and H be matrix Lie groups. A map \Phi from G to H is called a Lie group homomorphism if (1) \Phi is a group homomorphism and (2) \Phi is continuous.
