### Double Soul Conjecture

Recall the Soul Theorem of Cheeger and Gromoll: If \((M,g)\) is a complete and connected Riemannian manifold of non-negative sectional curvature, then there exists a closed, totally convex and totally geodesic embedded submanifold whose normal bundle is diffeomorphic to \(M\). Such a submanifold is called a soul of \((M,g)\) and the Riemannian metric induced on … Continue reading "Double Soul Conjecture"
