Properties of odd tangent bundle
1 Canonical odd vector field
1.1 General definition of
-parameter families of diffeomorphisms
In the language of functors of points, a

-parameter group of diffeomorphisms of a supermanifold

is
defined as a map, for any supermanifold

:
consistent with morphisms between different

’s.
1.2 Case of odd tangent bundle
For any supermanifold

, the

has a canonically defined

-parameter group of
diffeomorphisms. It is defined as follows. For any

define a “shift”:
Then define the map:
2 Odd tangent bundle of a group
If
is a supergroup, then
is again a supergroup.
