Bundle map

In mathematics, a bundle map (or bundle morphism) is a morphism in the category of fiber bundles. There are two distinct, but closely related, notions of bundle map, depending on whether the fiber bundles in question have a common base space. There are also several variations on the basic theme, depending on precisely which category of fiber bundles is under consideration.

The first three sections of this article discusses general fiber bundles in the category of topological spaces, while the fourth section provides other examples.
