Résumé : For each standard affine data satisfying some condition on the coroots, we define a group functor on the category of all rings which is a subgroup of some group functor R ↦ G(R[t, t-1]) ⋊ T (R), where G is a Chevalley scheme and T is a torus. This functor is then shown to satisfy the conditions of the five axioms required by [Ti4] to be a ‘minimal’ Kac-Moody group. © 1995, Belgian Mathematical Society. All Rights Reserved.
