abstract:

Kreck and Su have recently described, almost completely, the mapping class group of a smooth hypersurface in CP^4. There is a "monodromy" map from the fundamental group of the space of all smooth hypersurfaces in CP^4 to this mapping class group, and I will explain how the image of this map can be described. I will then give some idea of the differential topology methods which go into the proof.
