When… Expand PDF WebThe Geroch conjecture has been generalized in various ways. For instance, Chodosh and Li [CL20] proved the Geroch conjecture with arbitrary ends for 3 ≤ n ≤ 7 via the µ-bubble technique; namely, they proved for any n-manifold X, the connected sum Tn#X does not admit a complete metric of positive scalar curvature.
