Event description:

In a recent joint work with KyeongRo Kim and Hongtaek Jung, we show that a group of circle homeomorphisms is a 3-manifold group if it preserves a veering pair of invariant laminations. The proof has two parts - the topological part and dynamical part. We will try to explain both aspects. In some sense this is a partial converse to Thurston’s universal circle theorem.
