semigroup homomorphism between groups is
necessarily a
group homomorphism. A ring

between rings that preserves...
- mathematics, 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...

homomorphism sometimes means a map
which respects not only the
group structure (as above) but also the
extra structure. For example, a
homomorphism of...
- Then, for a
homomorphism f : G → H, (f(u),f(v)) is an arc (directed edge) of H
whenever (u,v) is an arc of G.
There is an
injective homomorphism from G to...

defined by the matrix. The
kernel of a
homomorphism is
reduced to 0 (or 1) if and only if the
homomorphism is injective, that is if the
inverse image...

composition of
module homomorphisms is
again a
module homomorphism, and the
identity map on a
module is a
module homomorphism. Thus, all the (say left)...

Monoid homomorphisms are
sometimes simply called monoid morphisms. Not
every semigroup homomorphism between monoids is a
