Abstract- We show that a discrete subgroup of SLn(R) generated by lattices in two opposite minimal horospherical subgroups is an arithmetic subgroup and we determine which arithmetic sub-groups can occur in this way. sous-groupes discrets de SLn(R) engendrés par des réseaux de sous-groupes horosphériques Résume ́- Nous montrons qu’un sous goupe dis-cret de SLn(R) engendre ́ par des réseaux dans deux sous-groupes horosphériques minimaux opposés est Typeset by AMS-TEX 1 un sous-groupe arithmétique et nous déterminons les sous-groupes arithmétiques engendrés de cette façon Version française abrégée- Un groupe algébrique G ⊂ GLn(C) est défini sur Q si un ensemble de polynômes sur Mn(C) définissant le groupe G ̃ peut être cho...
