Quasiconvex Foliations and Asymptotically Flat Metrics of Non-negative Scalar Curvature

Abstract: We prove that a broad subset of the space of asymptotically flat Riemannian metrics of nonnegative scalar curvature on R 3 is connected using a new method for prescribing scalar curvature that generalizes a method developed by Bartnik for quasi-spherical metrics.

“…Of course, this requires some pointwise a priori bounds on the solution u, but in the case that u is positive and bounded initially, these are easily obtained by the maximum principle under appropriate assumptions on the free data. The result of this is contained in the next lemma, whose proof can be found in [16,17], and is a slight generalization of a result contained in [2]. The proof is repeated here since it yields simple but important bounds on the components of the constructed metric.…”
