Abstract: For a product preserving gauge bundle functor on vector bundles, we present some lifts of smooth functions that are constant or linear on fibers, and some lifts of projectable vector fields that are vector bundle morphisms.

AMSclassification: primary 58A32.

Keywords: projectable vector field, Weil bundle, product preserving gauge bundle functor, lift.
