See this survey paper of Stolz. In addition, you might read the part about his conjectures on positive Ricci curvature. WebA result, first conjectured by Geroch, is proved to the extent, that the multipole moments of a static space-time characterize this space-time uniquely. As an offshoot of the proof one obtains an essentially coordinate-free algorithm for explicitly writing down a geometry in terms of it's moments in a purely algebraic manner. This algorithm seems suited for … dead final tour dates

"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. The case n= 3 was also " - Geroch conjecture

One case had a direct appeal to the geometers. This case says that if a metric has non-negative scalar curvature in ,R3 and if the metric is euclidean outside a compact set, then the metric is flat.
