Abstract: Sasakian manifolds are odd-dimensional Riemannian manifolds closely related to Kähler manifolds. After an introduction to this type of geometry we will focus on the symmetries induced by the Reeb vector field. We will report on some results on the global structure of Sasakian manifolds obtained by generalizing classical results on the fixed point sets of torus actions. The talk is based on joint work with Hiraku Nozawa and Dirk Töben.
