WebGeroch conjectured that all such axis-assessable solutions might be members of a group, and might be locally transformable into one another. Ernst and Hauser published the proof of this conjecture in 1981, by relating the transformation of these solutions to a homogeneous Hilbert problem.

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.

"WebGeroch conjecture has been validated in all dimensions: The Euclidean metrics on Rnfor all nadmit no non-trivial compactly sup-ported perturbations with Sc≥0. This (trivially) follows, for instance, from non-existence of metrics with Sc> 0 on the n-tori where the latter can be most easily proved by applying the index " - Geroch conjecture

WebJan 23, 2013 · In addition to the Geroch conjecture work by Schoen-Yau (see also the works of Gromov-Lawson here and here ), there have been a huge number of work on the question of which manifolds admit positive scalar curvature. See this survey paper of Stolz. In addition, you might read the part about his conjectures on positive Ricci curvature.

WebIn the Stanford conference in differential geometry, Geroch divided the conjecture into several special cases. 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. http://phys.iit.edu/~segre/iit_physics_bios/hauser_i.html
