DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/87/">Su
 bgroup separability in 3-manifold and free-by-cyclic groups</a>\nby Monika
  Kudlinska (University of Oxford) as part of Geometry and topology online\
 n\nLecture held in Room B3.02 in the Zeeman Building\, University of Warwi
 ck.\n\nAbstract\nA group \\(G\\) is said to be subgroup separable if every
  finitely generated subgroup of \\(G\\) is the intersection of finite inde
 x subgroups. It is known that a fundamental group of a compact\, irreducib
 le\, closed 3-manifold \\(M\\) is subgroup separable if and only if \\(M\\
 ) is geometric. We will discuss the problem of subgroup separability in fr
 ee-by-cyclic groups by drawing a parallel between free-by-cyclic and 3-man
 ifold groups. Time permitting\, we will discuss how to extend these ideas 
 to find non-separable subgroups in random groups.\n
