Juvitop Fall 2005

This is the Juvitop seminar webpage from Fall 2005, which was organized by John Francis about Surgery Theory. This site was originally hosted here. This is part of a deep copy of all prior Juvitop websites that I could find in the fall of 2016.

  • Surgery references:

    Andrew Ranicki's page is great, particularly the surgery bits and pieces.
    Kervaire-Milnor's classic groups of homotopy spheres.
    If one isn't feeling up to C.T.C. Wall's opus, Surgery on Compact Manifolds then Bill Browder's book, Surgery on Simply Connected Manifolds, is particularly comprehensible.
    Wolfgang Luck's introduction to surgery is available from ICTP.
