Pure Maths Colloquium: Geometries and Geometric Decompositions in Dimension 4

Presented by "Jonathan Hillman (University of Sydney, Australia)",

15 December 2003 16:00 in CM221

"A guiding principle for 3-Manifold Theory for the past quarter century has been the expectation that every closed 3-manifold should have a canonical decomposition into pieces with homogeneous geometries of finite volume. In this talk I shall consider the role of geometries for 4-manifolds, and I shall outline why most 4-manifolds do not admit such geometric decompositions. "
