In differential Geometry, a normal fiber is a particular kind of Fibré vectorial.
DefinitionThat is to say (M, G) a Variety riemannienne, and a subvariety riemannienne.
One defines, for , a vector with , i.e. normal with any vector , that is to say still for each one of these vectors v .
The unit of these vectors is called normal space with in .
Just as the total space of the tangent Fibré with a variety is built from all the tangent spaces with the variety, the total space of fiber normal with is defined by:
Fiber conormalThe fiber conormal is defined like the normal Fibré dual of fiber. It is a under-fiber of the Fibré cotangent.
