Titolo:	NET BUNDLES
Abstract:	Net bundles are at the same time a net and a bundle and can be constructed from a functor. A morphism then corresponds to a natural transformation. Fixing the two categories involved, the category of net bundles is isomorphic to the category of functors, This allows one to pass freely from ideas and concepts in category theory to those in the theory of bundles.
