On the 4-dimensional smooth Poincare Conjecture

4:00 pm Thursday, September 17, 2009
Robert Gompf (UT Austin)


The generalized Poincare Conjecture has now been settled in all dimensions, except for dimension 4 in the smooth category, where it remains as perhaps the last of the great classical problems of manifold topology. We will discuss the history of the problem, and recent developments that may call for reevaluating the likelihood that the conjecture is true.
