Duality in coordinates
Let us introduce some coordinates on .A generic -dimensional submanifold can be defined by the following equation,
depending on an odd parameter and an even parameter :
We conclude that may be
coordinatized with and .
Since is a functor, a vector field on should automatically define
some vector field on .
Theorem 2: The following vector field on :
defines the following vector field on :
where is defined as follows:
Proof:
