Connections and 1-jet fiber bundles
Connections for non-holonomic 3-webs
A non-holonomic 3-web is defined by two operators and such that is a projector, is involutory, and they are connected via the relation . The so-called parallelizing connection with respect to which the 3-web distributions are parallel is defined. Some simple properties of such connections are found.

Connections of higher order and product preserving functors
In this paper we consider a product preserving functor of order and a connection of order on a manifold . We introduce horizontal lifts of tensor fields and linear connections from to with respect to . Our definitions and results generalize the particular cases of the tangent bundle and the tangent bundle of higher order.

Constantes de Sobolev des arbres
Étant donnés et un arbre dont chaque sommet est de valence au moins , on étudie la constante de Sobolev d’exposant de , c’est-à-dire la plus petite constante telle que pour tout on ait . Notre motivation vient de la recherche de graphes finis avec des petites constantes de Poincaré d’exposant , en vue d’obtenir des exemples de groupes qui ont la propriété de point fixe sur les espaces .
Constantes explicites pour les inégalités de Sobolev sur les variétés riemanniennes compactes
L’objet de cette étude est de trouver des constantes explicites (dépendant d’un minimum d’invariants riemanniens et les plus faibles possible) dans différents types d’inégalités de Sobolev.
