Scalar curvature, mass, and harmonic mapsFor a 3dimensional Riemannian manifold there is a relationship between the level sets of a harmonic map and the manifold's scalar curvature, expressed by a formula discovered by Daniel Stern. We adopt this perspective to give a new bound for the mass of asymptotically flat initial data sets in terms of certain asymptotically linear functions. As a consequence, we obtain a new proof of the spacetime Positive Mass Theorem in dimension 3. These results are joint work with Hugh Bray, Sven Hirsch, Marcus Khuri, and Daniel Stern.
