Convex hulls and area minimizing currents in asymptotically locally hyperbolic manifolds

We solve the oriented asymptotic Plateau problem for integral currents of arbitrary codimension in conformally compact asymptotically locally hyperbolic manifolds without global curvature assumptions. This extends Anderson's theorem in hyperbolic space. A new ingredient is the construction of a barrier hull near conformal infinity, which serves as a barrier for area minimizing currents and stationary varifolds. In the conformally compact setting, the associated convex hull identity extends Anderson's result beyond globally pinched negative curvature.

A spacetime positive mass theorem with corners via mollification

We prove a strict dominant energy deformation theorem for asymptotically flat initial data with corners along a hypersurface $Σ$. The deformation preserves a corner condition on the Bartnik data across $Σ$. We show that if the dominant energy condition holds on each side of $Σ$ and the Bartnik data satisfy this corner condition, then the exterior end satisfies $E \ge |P|$ in every dimension $n \ge 3$.
