Geometry and Topology Seminar: Stable diffeomorphism of 4-manifolds

Presented by Daniel Kasprowski, Universitat Bonn

7 December 2017 13:00 in CM221

The diffeomorphism classification of 4-manifolds is a very hard problem. But it gets considerably easier when one allows connected sums with complex projective planes. In this talk I will show that the stable diffeomorphism type in this sense is often determined by the Postnikov 2-type of the manifold. This is joint work with Mark Powell and Peter Teichner.
