The primary source is the seminal 1963 differential-topology article, "Groups of homotopy spheres," by Michel Kervaire and John Milnor.

 

Sean Corrigan will continue in Section 5.  He will show, for a highly connected odd-dimensional parallelizable manifold, how to do parallelizable surgery to produce a new manifold with only torsion in the middle-dimensional homology groups.  This will involve a more detailed look at the effect of a surgery near the middle dimension.

 

(For continuity, here's a link to the previous talk.)
