A bundle map is a map between bundles along with a compatible map between the base manifolds. Suppose and
are two bundles, then

is a bundle map if there is a map such that
for all
. In particular, the fiber bundle of
over a point
, gets mapped to the fiber of
over
.
In the language of category theory, the above diagram commutes. To be more precise, the induced map between fibers has to be a map in the category of the fiber. For instance, in a bundle map between vector bundles the fiber over is mapped to the fiber over
by a linear transformation.
For example, when is a smooth map between smooth manifolds then
is the differential, which is a bundle map between the tangent bundles. Over any point in
, the tangent vectors at
get mapped to tangent vectors at
by the Jacobian.
