Abstract

In this paper algebraic properties of convex sets are studied. In the first section we present one of our main results which is an algebraic order cancellation law of convex sets. Then we study properties of convex pairs and reduced pairs mainly within the general frame of commutative semigroups which satisfy the order cancellation law.
