Explicit Ricci-flat metrics on a special Schoen threefold

Jixiang Fu, Jiuhe Liu, Yunyang Xiao +1

We give an explicit convergent representation of the Ricci-flat Kähler metric in a one-parameter family of classes on a fixed special Schoen threefold. The threefold resolves a shi…

Explicit Ricci-flat Metrics on Kummer K3 Surfaces

Jixiang Fu, Yunyang Xiao, Shing-Tung Yau

We give a convergent explicit representation of the Ricci-flat Kähler metrics supplied by the Calabi--Yau theorem in a one-parameter family of classes on a fixed Kummer K3 surface.…

Positive Sectional Curvature on All Smooth 7-spheres

Yang-Hui He, Ziran Liu, Shing-Tung Yau

We construct a smooth Riemannian metric with strictly positive sectional curvature on every smooth homotopy seven-sphere. For each smooth structure, we construct positively curved…

Divisorial Rigidity and Regularity of Boundary Cases for the Supercritical LYZ Equation

Jixiang Fu, Shing-Tung Yau, Dekai Zhang +1

We study the supercritical LYZ equation on compact Kähler manifolds at the boundary of stability. Under numerical semistability, we prove a quantitative positivity estimate on the…

Compact Proof of the Positivity of Quasi-Local Masses for a class of Initial Data

Puskar Mondal, Shing-Tung Yau

We prove a purely quasi-local positivity theorem for the Wang--Yau mass for a class of initial data whose Jang deformation, after a boundary-preserving conformal reduction to zero…

On Compact Hermitian Surfaces With Positive Strominger-Bismut Sectional Curvature

Qingsong Wang, Shing-Tung Yau, Fangyang Zheng

In an earlier work, Yau and Zheng proposed a Hermitian analogue of a weak form of the Frankel conjecture, which states that any compact Hermitian manifold with positive Strominger-…

Orthogonal complex structures on flat tori

Qingsong Wang, Shing-Tung Yau, Fangyang Zheng

We classify compact Hermitian manifolds with flat Levi-Civita connection. This is equivalent to the classification of all orthogonal complex structures on flat tori. It generalized…

Volume Stability for Hyperbolic Manifolds and Applications to General Relativity

Puskar Mondal, Shing-Tung Yau

We prove a sharp volume-stability theorem for closed hyperbolic three-manifolds. Let \((M,h)\) be closed hyperbolic with \(\operatorname{Ric}_h=-2h\), and let \(g_i\) be smooth met…
