Hermitian threefolds with constant holomorphic sectional curvature

Shuwen Chen, Fangyang Zheng

An old conjecture in non-Kähler geometry states that if the Chern holomorphic sectional curvature of a compact Hermitian manifold is equal to a constant , then the metric must b…

Hermitian connections with parallel torsion and constant holomorphic sectional curvature

Shuwen Chen, Fangyang Zheng

A long-standing conjecture in non-Kähler geometry states that a compact Hermitian manifold with constant Chern holomorphic sectional curvature should be Kähler when the constant is…

Hermitian Connections with Parallel Torsion and the Fino--Vezzoni Conjecture

Shuwen Chen, Fangyang Zheng

We prove that the Fino--Vezzoni conjecture holds on every compact complex manifold carrying a Hermitian connection with parallel torsion. More precisely, if a compact connected com…

The Fino-Vezzoni conjecture on balanced Bismut torsion-parallel manifolds

Shuwen Chen, Fangyang Zheng

We study the Fino-Vezzoni conjecture on compact complex manifolds carrying a balanced Bismut torsion-parallel Hermitian metric. We prove that if such a manifold also admits a pluri…

Flat Hermitian Lie algebras are Kähler

Dongmei Zhang, Fangyang Zheng

In 1976, Milnor classified all Lie groups admitting a flat left-invariant metric. They form a special type of unimodular 2-step solvable groups. Considering Lie groups with Hermiti…

On Hermitian manifolds with constant mixed curvature

Shuwen Chen, Fangyang Zheng

In a recent work, Kai Tang conjectured that any compact Hermitian manifold with non-zero constant mixed curvature must be Kähler. He confirmed the conjecture in complex dimension $…
