DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/90/">St
 retch laminations and hyperbolic Dehn surgery</a>\nby Cameron Gates Rudd (
 MPI Bonn) as part of Geometry and topology online\n\nLecture held in Room 
 B3.02 in the Zeeman Building\, University of Warwick.\n\nAbstract\nGiven a
  hyperbolic manifold \\(M\\) and a homotopy class of maps from \\(M\\) to 
 the circle\, there is an associated geodesic "stretch" lamination encoding
  at which points in \\(M\\) the Lipschitz constant of any map in the homot
 opy class must be large. Recently\, Farre-Landesberg-Minsky related these 
 laminations to horocycle orbit closures in infinite cyclic covers and when
  \\(M\\) is a surface\, they analyzed the possible structure of these lami
 nations. I will discuss the case where \\(M\\) is a 3-manifold and give th
 e first 3-dimensional examples where these laminations can be identified. 
 The argument uses the Thurston norm and tools from quantitative Dehn surge
 ry.\n
