Webused to study Massey products. More precisely, Massey products may be interpreted as intersections of geodesiePoincars imodelné the. These elements are called minimal Massey products and are the analogue of Massey products over a system considered in Porter's paper. They enjoy the property of being uniquely defined (without indeterminacy) and of WebHigher order Massey products were introduced in [ 16] and generalized in [ 18]. These are of fundamental importance not only in the study of differential graded algebras (DGA’s, henceforward) per se, but also in those geometrical contexts where DGA’s play a role.
