Given a group action and a principal bundle , the associated fiber bundle on is
(1) |
In particular, it is the quotient space where .
For example, the torus has a action given by
(2) |
and the frame bundle on the sphere,
(3) |
is a principal bundle. The associated fiber bundle is a fiber bundle on the sphere, with fiber the torus. It is an example of a four-dimensional manifold.
