A Lie group of transformations of A is said to be inessential if there exists anH-structure B in A such that Aut(B). The aim of this paper is to impose conditions onM, G,H,A and so that is inessential.engGroups of transformations of a G-structure which leave invariant a substructurejournal articlehttp://www.collectanea.ub.edu/index.php/Collectanea/issue/view/614http://www.springer.com/mathematics/applications/journal/13348open access514.7Invariant substructureG-structureLie group of transformationsGeometría diferencial1204.04 Geometría Diferencial
