Dans ce travail, nous étudions les fibrés uniformes de Steiner de type k, ou k est le degré le plus bas de la décomposition. Nous prouvons des limites supérieures et inférieures strictes pour le rang dans le cas k=1 et, de plus, nous donnons des familles d’exemples pour chaque rang possible et nous expliquons quelle relation existe entre les familles. Après avoir traité le cas k en général, nous conjecturons que chaque fibré uniforme de Steiner de type k est obtenu par la technique de construction proposée.

In this work we study k-type uniform Steiner bundles, being k the lowest degree of the splitting. We prove sharp upper and lower bounds for the rank in the case k=1 and moreover we give families of examples for every allowed possible rank and explain which relation exists between the families. After dealing with the case k in general, we conjecture that every k-type uniform Steiner bundle is obtained through the proposed construction technique.
