Abstract

Despite being a vast generalization of Garside groups, right \ell-groups with noetherian lattice structure and strong order unit share a lot of the properties of Garside groups. In the present work, we prove that every modular noetherian right \ell-group with strong order unit decomposes as a direct product of beams, which are sublattices that correspond to the directly indecomposable factors of the strong order interval. Furthermore, we show that the beams of dimension δ4\delta \geq 4 can be coordinatized by the RR-lattices in QδQ^{\delta}, where QQ is a noncommutative discrete valuation field with valuation ring RR. In particular, this gives a precise description of a very big family of modular Garside groups.
