Positive Ricci Curvature on Twisted Suspensions

International Mathematics Research Notices
Abstract The twisted suspension of a manifold is obtained by surgery along the fibre of a principal circle bundle over the manifold. It generalizes the spinning operation for knots and preserves various topological properties. In this article, we show that Riemannian metrics of positive Ricci curvature can be lifted along twisted ...
