4-Manifolds are Broken, Achiral, Lefschetz Fibrations
Geometry/Topology| Speaker: | Robion Kirby, Univ Cal Berkeley |
| Location: | 2112 MSB |
| Start time: | Wed, May 23 2007, 4:10PM |
Description
The talk will mostly consist of an explanation of the terms in the
theorem of the title. In particular, I'll begin with a description of
elliptic surfaces as Lefschetz fibrations which will take much of the hour,
and then the generalizations to achiral and broken.
