RC-positivity and rigidity of harmonic maps into Riemannian manifolds

Jun Wang, Xiaokui Yang

In this paper, we show that every harmonic map from a compact Kähler manifold with uniformly RC-positive curvature to a Riemannian manifold with non-positive complex sectional curv…

RC-positivity and scalar-flat metrics on ruled manifolds

Jun Wang, Xiaokui Yang

Let $X$ be a ruled surface over a curve of genus $g$ . We prove that $X$ has a scalar-flat Hermitian metric if and only if $g \geq 2$ and $m (X) > 2 - 2 g$ where $m (X)$ is an intrinsic num…

A refined study of Mazur's Eisenstein theory

Jun Wang

We apply the methods of Fukaya, Kato and Sharifi to refine Mazur's study of the Eisenstein ideal. Given prime numbers $N$ and $p \geq 5$ such that $p ∣ φ (N)$ , we study the quotien…

Large scaled geometry of Julia sets of entire and meromorphic functions

Jun Wang, Xiao Yao

In this paper, we study the large scaled geometric structure of Julia sets of entire and meromorphic functions. Roughly speaking, the structure gives us some asymptotic information…
