In joint work with Gadde Swarup and Vincent Guirardel, we have proved a generalization of the Algebraic Torus Theorem, which was proved by Dunwoody and Swenson. In this talk, I will start by discussing the Algebraic Torus Theorem, and how it is related to the topology of surfaces and 3-manifolds. Then I will indicate what a relative version of this result looks like and why low dimensional topology makes it natural to consider such a thing. Finally I will very briefly discuss the key ideas in our work, and discuss some applications.
