- On the categorical behaviour of preordered groupsPublication . Clementino, Maria Manuel; Martins-Ferreira, Nelson; Montoli, AndreaWe study the categorical properties of preordered groups. We first give a description of limits and colimits in this category, and study some classical exactness properties. Then we point out a strong analogy between the algebraic behaviour of preordered groups and monoids, and we apply two different recent approaches to relative categorical algebra to obtain some homological properties of preordered groups.
