SUMMARY:Cameron Rudd (Oxford): Stretch laminations via hyperbolic Dehn surg
 ery
DESCRIPTION:Cameron Rudd: Given a hyperbolic manifold M and a homotopy clas
 s of maps from M to the circle\, there is an associated geodesic "stretch"
  lamination encoding at which points in M the Lipschitz constant of an opt
 imal map in the homotopy class must be large. I will discuss these laminat
 ions in the context of different norms on the cohomology of a hyperbolic 3
 -manifold and discuss how to give the first 3-dimensional examples where 
 these laminations can be identified.
