Iterative construction of Hermitian-Einstein metrics on stable bundles

Jiaxuan Fan, Zhiyao Xiong, Xiaokui Yang +1

Let be a stable holomorphic vector bundle over a compact Kähler (or Gauduchon) manifold . We show that for any real number and any initial Hermitian metric …

The prescribed Hermitian-Yang-Mills flow II

Zhiyao Xiong, Xiaokui Yang, Shing-Tung Yau

We prove an analogue of the classical Donaldson-Uhlenbeck-Yau theorem by using the prescribed Hermitian-Yang-Mills flow. Let be a holomorphic vector bundle over a compact Kähle…

Laplacian comparison theorems on complete Kähler manifolds and applications

Jiaxuan Fang, Zhiyao Xiong, Xiaokui Yang

In this paper, we establish new Laplacian comparison theorems and rigidity theorems for complete Kähler manifolds under new curvature notions that interpolate between Ricci curvatu…

RC-positivity, Schwarz's lemma and comparison theorems

Zhiyao Xiong, Xiaokui Yang, Shing-Tung Yau

It is well-known that the classical Schwarz lemma yields an explicit comparison of two Hermitian metrics with uniform constant negative curvature bounds through holomorphic maps be…

Conjugate radius, volume comparison and rigidity

Zhiyao Xiong, Xiaokui Yang

In this paper, we prove conjugate radius estimate, volume comparison and rigidity theorems for Kähler manifolds with various curvature conditions.
