DESCRIPTION:Title: <a href="https://researchseminars.org/talk/rlgts/4/">In
 stanton Floer homology and the depth of taut foliations</a>\nby Zhenkun Li
  (MIT) as part of Regensburg low-dimensional geometry and topology seminar
 \n\n\nAbstract\nSutured manifold hierarchy is a powerful tool introduced b
 y Gabai to study the topology of 3-manifolds. The length of a sutured mani
 fold hierarchy gives us a measurement of how complicated the sutured manif
 old is. Also\, using this tool\, Gabai proved the existence of finite dept
 h taut foliations. However\, he didn’t discuss how finite the depth coul
 d be.\nSutured Instanton Floer homology was introduced by Kronheimer and M
 rowka and is defined on balanced sutured manifolds. In this talk\, I will 
 explain how sutured instanton Floer homology could offer us bounds for the
  minimal length of a sutured hierarchy and the minimal depth of a foliatio
 n on a fixed balanced sutured manifold.\n
