embedding
Let and be manifolds and a smooth map. Then is an embedding if
-
1.
is a submanifold of , and
-
2.
is a diffeomorphism. (There’s an abuse of notation here. This should really be restated as the map defined by is a diffeomorphism.)
The above characterization can be equivalently stated: is an embedding if
-
1.
is an immersion, and
-
2.
by abuse of notation, is a homeomorphism.
Remark. A celebrated theorem of Whitney states that every dimensional manifold admits an embedding into .
