Abstract: |
The goal of this talk is to give an overview of Brieskorn manifolds, and the role they played in differential topology, contact topology and Sasakian geometry. A Brieskorn manifold can be defined as the link of a singular affine variety of the form $$ \{ (z_0,\ldots, z_n) \in \C^{n+1} | \sum_{i=0}^n z_i^{a_i}=0 \} $$ In the lowest dimension Brieskorn manifolds are torus links embedded in S^3. Despite their very simple nature, they have given explicit models of exotic spheres, exotic contact structures, and new Einstein metrics on spheres. |
