Abstract
Using the covariant derivative for exterior forms of a (dual) vector bundle, the complete lift of an arbitrary section of a (dual) vector bundle is discovered. A theory of Legendre type and Legendre duality between vertical lifts and between complete lifts are presented. Finally, a duality between Lie algebroids structures is developed
Highlights
The Sasaki lift of a Riemannian metric structure on M is an important example of metric structures on T M which is used in di¤erential geometry with many applications in physics [19]
Lifts of geometrical structures of T M to T T M were introduced and studied by several authors [8, 9, 10, 11, 20]. In many papers such as [5, 12, 14, 17, 18], the authors studied the lifts of geometric objects to the second order tangent bundle, tensor bundle and jet bundle
