Foliation of area-minimizing hypersurfaces in asymptotically flat manifolds of higher dimension

Shihang He, Yuguang Shi, Haobin Yu

We prove the existence of foliations by area-minimizing hypersurfaces in asymptotically flat (AF) manifolds with arbitrary dimension and arbitrary ends. Also we provide behaviors o…

Capillary prisms, Coxeter gluing, and the -systole of 3-manifolds with positive scalar curvature

Shihang He, Chao Li

The paper develops new estimates for the π₂‑systole of three‑dimensional manifolds with positive scalar curvature using capillary prism building blocks and a Coxeter‑gluing techniq…

Positive mass theorems on singular spaces and some applications

Shihang He, Yuguang Shi, Haobin Yu

Building upon dimension reduction techniques in the study of positive scalar curvature (PSC) geometry, we prove an effective version of the positive mass theorem (PMT) for asymptot…

Singularity removal rigidity theorems for minimal hypersurfaces in manifolds with nonnegative scalar curvature

Shihang He, Yuguang Shi, Haobin Yu

We prove two "Singularity removal rigidity theorems" for minimal hypersurfaces with isolated singularities in manifolds of nonnegative scalar curvature (Theorems \ref{thm: rigidity…

A proof for the Riemannian positive mass theorem up to dimension 19

Yuchen Bi, Tianze Hao, Shihang He +2

In this paper, we prove the Riemannian positive mass theorem up to dimension , building on a combination of torical symmetrization and the singularity blow-up technique develop…

Twisted stability and positive scalar curvature obstruction on fiber bundles

Shihang He

We establish several non-existence results of positive scalar curvature (PSC) on fiber bundles. We show that under an incompressible condition of the fiber, for a Cartan-Hada…

A note on rational homology vanishing theorem for hypersurfaces in aspherical manifolds

Shihang He, Jintian Zhu

In this note, we generalize Gromov's reduction \cite{Gro20} from the aspherical conjecture to the generalized filling radius conjecture to the smooth -homology vanishing…

Relative aspherical conjecture and higher codimensional obstruction to positive scalar curvature

Shihang He

Motivated by the solution of the aspherical conjecture up to dimension 5 [CL20][Gro20], we want to study a relative version of the aspherical conjecture. We present a natural condi…

Foliation of area minimizing hypersurfaces in asymptotically flat manifolds and Schoen's conjecture

Shihang He, Yuguang Shi, Haobin Yu

In this paper, we demonstrate that any asymptotically flat manifold with can be foliated by a family of area-minimizing hypersurfaces, each of which is a…
