The h-cobordism theorem and its dimension 4 failure

4 February 2015
Gareth Wilkes

This talk will give an almost complete proof of the h-cobordism theorem, paying special attention to the sources of the dimensional restrictions in the theorem. If time allows, the alterations needed to prove its cousin, the s-cobordism theorem, will also be sketched.
