Title: 4 manifold revisited

Speaker: Peter Teichner (Max Planck Institute for Mathematics & UC Berkeley)

Abstract: We explain the classification of low-dimensional manifolds from first principles, with an emphasis on dimension four. We will make an attempt to make 4-dimensional visualizations of such space-times understandable for a general audience.
