These geometries are basic structures in combinatorial convexity, because any convex geometry can be generated from them. In this note, we will give a necessary and sufficient condition on the closure operator which leads us to a new characterization of poset geometry.Alan BrettoEnzo Maria Li MarziFrancesco Rania
