DESCRIPTION:Title: <a href="https://researchseminars.org/talk/mitgt/13/">F
 illing links in 3-manifolds</a>\nby Slava Krushkal as part of MIT Geometry
  and Topology Seminar\n\nAbstract: TBA\n\nI will discuss the notion of fil
 ling links in 3-manifolds: a link is filling if any 1-spine of the 3-manif
 old\, disjoint from the link\, injects into the link complement on the lev
 el of the fundamental group. I will give a construction of links in the 3-
 torus which are filling modulo terms of the lower central series\; the pro
 of relies on a new extension of the Stallings theorem. I will also discuss
  the construction of Leininger and Reid of filling links and spines in 3-m
 anifolds of rank 2\, and formulate some open problems. (Joint work with Mi
 chael Freedman)\n
