For example, the gauge potentials are identified as differential one-forms on the manifold. The Lagrangian densities invariant under the algebra of the infinitesimal gauge transformations are also disscussed. From the set of these Lagrangians, the class of variationally trivial Lagrangians is interpreted in terms of multivector fields on the ground manifold.engjournal articlehttp://scitation.aip.org/content/aip/journal/jmp/40/2/10.1063/1.532687http://jmp.aip.org/restricted access514.142517.95Lagrangian mechanicsLie algebras.Geometria algebraicaEcuaciones diferenciales1201.01 Geometría Algebraica1202.07 Ecuaciones en Diferencias
