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…

Comparison theorems in Hermitian geometry I
Xiaokui Yang
This paper develops second variational formulas and index forms in the context of Hermitian geometry. Building upon these analytical foundations, we establish results analogous to…

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…
