WebbIt tells us that an intersection norm on a surface (respectively the Thurston norm on a 3-manifold) encodes the open book decompositions of the unit tangent bundle of that surface (respectively the topology of foliated 3- manifold). Our purpose in this article is to study intersection norms for their own sake.
