Duality in coordinates
Let us introduce some coordinates 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:
