A positive mass theorem for asymptotically flat manifolds with a non-compact boundary

Abstract: We define a mass-type invariant for asymptotically hyperbolic manifolds with a non-compact boundary which are modelled at infinity on the hyperbolic half-space and prove a sharp positive mass inequality in the spin case under suitable dominant energy conditions. As an application we show that any such manifold which is Einstein and either has a totally geodesic boundary or is conformally compact and has a mean convex boundary is isometric to the hyperbolic half-space.

“…have played an important role in such prescribed conformal curvature problems. As a direct consequence of Theorem 1.3 and the positive mass type theorem recently proved in [3], we obtain Theorem 1.4. Let (M, g 0 ) be a smooth compact Riemannian manifold of dimension n ≥ 3 with boundary.…”

“…The definition of the mass m(g) was first proposed by Marques. The following positive mass type conjecture was initially given in [2] and has been verified in [3,Theorem 1.3] under the hypotheses that either 3 ≤ n ≤ 7 or if n ≥ 3 and N is spin.…”

“…The above definition is independent of the particular choice of the chart at infinity what means that the mass is a geometric invariant. As already mentioned, we also have a Positive mass theorem in this context (see [1], Theorem 1.1), which states that an asymptotically flat manifold with non-negative scalar curvature and mean convex boundary has nonnegative mass if either 3 ≤ n ≤ 7 or n ≥ 3 and M is spin. Moreover the mass is zero if only if it is isometric to R n + with the flat metric.…”

“…The hypersurface flows in the outward normal direction with speed N = 1 H and it is easy to see that there is a problem if either H = 0 or H changes the sign on Σ t . 1 To overcome theses problems, Marquadt [20,22] developed the notion of weak solutions for (2.2), proving the existence and uniqueness of such solutions guided by the ideas of Huisken and Ilmanen [12].…”
