Type problem, the first eigenvalue and Hardy inequalities

Gilles Carron, Bo-Yong Chen, Yuanpu Xiong

In this paper, we study the relationship between the type problem and the asymptotic behaviour of the first (Dirichlet) eigenvalues of ``balls'' on a comp…

Type problem and the first eigenvalue

Bo-Yong Chen, Yuanpu Xiong

In this paper, we study the relationship between the type problem and the asymptotic behavior of the first eigenvalues of ``balls'' on a complete Riemanni…

Minimal and Ohsawa-Takegoshi extensions

Yuanpu Xiong

We find a precise relationship between the minimal extensions in and Ohsawa-Takegoshi extension theorems. This relationship also gives another proof to the versio…

A Psh Hopf Lemma for Domains with Cusp Conditions

Bo-Yong Chen, Yuanpu Xiong

We obtain a psh Hopf lemma for domains satisfying certain cusp conditions by using a sharp estimate for the Green function of a planar cusp along the axis. As an application, we ob…
