Improved theorem on curvature and manifold symmetry.
Proves positive Euler characteristic for certain manifolds with positive second intermediate Ricci curvature.
We prove that an integral homology 3-sphere is S^3 if and only if it admits four periodic diffeomorphisms of odd prime orders whose space of orbits is S^3. As an application we show that an irreducible integral homology sphere which is not S^3 is the cyclic branched cover of odd prime order of at most four knots in S^3…
