Topology/Geometry Seminar

Revisit the theory of laminar groups

Hyungryul Baik (KAIST)

Location:  Hill Center; Room 705
Date & time: Tuesday, 13 September 2022 at 4:00PM - 5:00PM

I will give a brief introduction to laminar groups which are groups of orientation-preserving homeomorphisms of the circle admitting invariant laminations. The term was coined by Calegari and the study of laminar groups was motivated by work of Thurston and Calegari-Dunfield. We present old and new results on laminar groups which tell us when a given laminar group is either fuchsian or Kleinian.
