However , there is a category of above mentioned natural bundles T \ to X which admit the functorial lift \ widetilde \ tau onto T of any vector field \ tau on X such that \ tau \ to \ widetilde \ tau is a Lie algebra monomorphism This functorial lift \ widetilde \ tau is an infinitesimal general covariant transformation of T. In a general setting , one considers a monomorphism f \ to \ widetilde f of a group of diffeomorphisms of X to a group of bundle automorphisms of a natural bundle T \ to X. Automorphisms \ widetilde f are called the general covariant transformations of T. For instance , no vertical automorphism of T is a general covariant transformation .
