Scalar curvature rigidity of small spherical caps with arbitrary fill-ins

Yiyue Zhang, Bowen Zhao

We prove an analogue of Min-Oo's conjecture for sufficiently small spherical caps in the unit round sphere. For every dimension , there exists such that the follo…

Stability of the Riemannian positive mass theorem in all dimensions

Gaoming Wang, Yiyue Zhang

We prove stability of the Riemannian positive mass theorem in all dimensions, extending the Dong-Song stability theorem. For a sequence of complete asymptotically flat manifolds wi…

Classification of Maximally Charged Black Holes

Sven Hirsch, Yiyue Zhang

We characterize all maximally charged black hole spacetimes in dimensions. More precisely, given any initial data set saturating the mass-charge inequality that sat…

The Hyperboloidal and Spacetime Positive Mass Theorem in All Dimensions

Sven Hirsch, Marcus Khuri, Martin Lesourd +1

Using the recent work of Brendle--Wang on the Riemannian positive mass theorem, we prove the spacetime positive mass theorem for asymptotically flat and asymptotically hyperboloida…

The Spacetime Positive Mass Theorem with Multiple Time Dimensions

Sven Hirsch, Alec Payne, Yiyue Zhang

We generalize the spacetime positive mass theorem to include multiple time dimensions. In particular, we show that the mass remains nonnegative in the sense that the energy is…

Causal character of imaginary Killing spinors and spinorial slicings

Sven Hirsch, Yiyue Zhang

We characterize spin initial data sets that saturate the BPS bound in the asymptotically AdS setting. This includes both gravitational waves and rotating black holes in higher dime…

Rigidity of Asymptotically Hyperboloidal Initial Data Sets with Vanishing Mass

Sven Hirsch, Hyun Chul Jang, Yiyue Zhang

In Special Relativity, massless objects are characterized as either vacuum states or as radiation propagating at the speed of light. This distinction extends to General Relativity…

Initial data sets with vanishing mass are contained in pp-wave spacetimes

Sven Hirsch, Yiyue Zhang

In 1981, Schoen-Yau and Witten showed that in General Relativity both the total energy and the total mass of an initial data set modeling an isolated gravitational system a…

Stability of Llarull's theorem in all dimensions

Sven Hirsch, Yiyue Zhang

Llarull's theorem characterizes the round sphere among all spin manifolds whose scalar curvature is bounded from below by . In this paper we show that if the scalar c…

The case of equality for the spacetime positive mass theorem

Sven Hirsch, Yiyue Zhang

The rigidity of the spacetime positive mass theorem states that an initial data set satisfying the dominant energy condition with vanishing mass can be isometrically embe…
