Convex chains in lattice monoids and lattice loops

Abstract. One of the central results of the early theory of lattice ordered groups is a theorem due to Ján Jakubik, telling that a maximal convex chain containing the identity element is a direct factor. In this paper it is shown --- along the lines of Bigard--Keimel--Wolfenstein --- how far this result carries over to divisibility semigroups and divisibility semiloops.
