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…

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…

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…

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…

Finite generation of Noether-Lefschetz divisors and the slope of the moduli space of cubic fourfolds

Ignacio Barros, Shi He, Paul Kiefer

We study divisors on moduli spaces of cubic fourfolds with simple singularities and of quasi-polarized K3 surfaces of degree . For the moduli space of cubic fourfolds, we intro…

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…
