Metrizability of the Lie algebroid generalized tangent bundle and (generalized) Lagrange $(ρ,η)$-spaces

A class of metrizable vector bundles in the general framework of generalized Lie algebroids have been presented in the eight reference. Using a generalized Lie algebroid we obtain the Lie algebroid generalized tangent bundle of a vector bundle. This Lie algebroid is a new example of metrizable vector bundle. A new class of Lagrange spaces, called by use, generalized Lagrange (ρ?;η?)-space, Lagrange (ρ?;η?)-space and Finsler (ρ?;η?)-space are presented. In the particular case of Lie algebroids, new and important results are presented. In particular, if all morphisms are identities morphisms, then the classical results are obtained.

The metrizability of the generalized tangent bundle of dual of a vector bundle

Two new classes of metrizable vector bundles have been presented in the papers [1] and [4]. The Lie algebroid generalized tangent bundle of a dual vector bundle is presented. This Lie algebroid is a new example of metrizable vector bundle. A new class of Hamilton spaces, called by use, generalized Hamilton (ρ,η)-space, Hamilton (ρ,η)-space and Cartan (ρ,η)-space are presented. The results obtained in the particular case of Lie algebroids emphasize the importance and the utility of our new method by work. In particular, if all morphisms are identities morphisms, then the classical results are obtained.

Legendre Duality Between Lagrangian and Hamiltonian Mechanics

In some previous papers, a Legendre duality between Lagrangian and Hamiltonian Mechanics has been developed. The (ρ,η)-tangent application of the Legendre bundle morphism associated to a Lagrangian L or Hamiltonian H is presented. Using that, a Legendre description of Lagrangian Mechanics and Hamiltonian Mechanics is developed. Duality between Lie algebroids structure, adapted (ρ,η)-basis, distinguished linear (ρ,η)-connections and mechanical (ρ,η)-systems is the scope of this paper. In the particular case of Lie algebroids, new results are presented. In the particular case of the usual Lie algebroid tangent bundle, the classical results are obtained.

Hamiltonian Mechanics on Duals of Generalized Lie Algebroids

A new description, different by the classical theory of Hamiltonian Mechanics, in the general framework of generalized Lie algebroids is presented. In the particular case of Lie algebroids, new and important results are obtained. We present the \emph{dual mechanical systems} called by use, \emph{dual mechanical}$(ρ,η) $\emph{-systems, Hamilton mechanical}$(ρ,η) $\emph{-systems} or \emph{% Cartan mechanical}$(ρ,η) $\emph{-systems.} and we develop their geometries. We obtain the canonical $(ρ,η) $\emph{-}semi(spray) associated to a dual mechanical $(ρ,η) $-system. The Hamilton mechanical $(ρ,η)$-systems are the spaces necessary to develop a Hamiltonian formalism. We obtain the $(ρ,η)$-semispray associated to a regular Hamiltonian $H$ and external force $F_{e}$ and we derive the equations of Hamilton-Jacobi type.

The generalized Lie algebroids and their applications

In this paper we introduce the notion of generalized Lie algebroid and we develop a new formalism necessary to obtain a new solution for the Weistein's Problem. Many applications emphasize the importance and the utility of this new framework determined by the introduction of generalized Lie algebroids.
