Let G be an algebraic group defined, over Q. We assume that G c GL(n, C). Let Gz = G n SL(n, Z), and for any ideal accZ, let Ga =G SL(n, a) where SL(n, a) is the kernel of the natural map SL(n, Z) > SL(n, Z/a). Let F be an arithmetic subgroup of G, i.e., a subgroup such that r n Gz is of finite index in both F and Gz. For such an arithmetic subgroup of G, we denote by E(F) the subgroup of F generated by all the unipotent elements contained in it. With this notation, we can state our main result.
