Abstract

Abstract We provide geometric realizations of both classical and “exotic” $G$-manifolds such as spheres, Kervaire manifolds, bundles over spheres, homogeneous spaces, and connected sums among them. As an application, we apply the process known as Cheeger deformation to produce new metrics of both positive Ricci and almost non-negative curvature on such objects.
