Abstract: |
As Cheeger and Gromoll showed, an open manifold with a metric of non-negative sectional curvature is diffeomorphic to the normal bundle of certain totally convex closed submanifold, called the soul. It is possible to construct open manifolds with two or more such metrics whose souls are "different": we will review previous examples and we will construct open manifolds with non-homeomorphic positively curved souls. To do that we will study some properties of Eschenburg spaces, an infinite family of positively curved manifolds. |
Hierzu ergeht herzliche Einladung. |
