On the Geometry of Cohomogeneity One Manifolds with Positive Curvature,s have this property, but some potential families for new examples in dimension 7 arise as well. We discuss the geometry of these known examples and the connection that the candidates have with self-dual Einstein metrics..There are very few known examples of manifolds with positive sectional curvatu

The Sasaki Cone and Extremal Sasakian Metrics,whose Sasaki cone coincides with the extremal set, and examples where the extremal set is empty. We end up by proving that a conjecture of Orlik concerning the torsion of the homology groups of these links holds in the five-dimensional case.
