Sormani's scalar curvature conjecture for intrinsic flat limits
Sormani's scalar curvature conjecture for intrinsic flat limits
Let be a sequence of three-dimensional Riemannian manifolds. Write for the scalar curvature, for their volume, and for the minimal area of a closed minimal surface in . Assume
Suppose that converges in the intrinsic flat sense to , written . For , let be the metric ball in the limit space, let denote its volume, and let denote the Euclidean volume of a radius- ball. Sormani's scalar curvature conjecture. At every point ,
This is proposed as a possible revision of Gromov's vague conjecture, motivated by counterexamples showing that intrinsic flat and Gromov--Hausdorff limits of noncollapsing sequences with positive scalar curvature may fail to retain key properties of nonnegative scalar curvature. The statement remains open in the supplied source.
