- not preserved, one has a rng
homomorphism. A
linear map is a
homomorphism of
vector spaces; that is, a
group homomorphism between vector spaces 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...
-
kernel of a
homomorphism is the
relation describing how
elements in the
domain of the
homomorphism become related in the image. A
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...
-
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)...
- of two
objects between which a
homomorphism is given, and of the
kernel and
image of the
homomorphism. The
homomorphism theorem is used to
prove the isomorphism...
- In mathematics,
especially in
algebraic topology, an
induced homomorphism is a
homomorphism derived in a
canonical way from
another map. For example, a...
