On the Method of Solution for the Non-Homogeneous Generalized Riemann-Hilbert Boundary Value Problems
《Chinese Quarterly Journal of Mathematics》2024年第3期262-269,共8页ZHANG Wen-wen LI Ping-run 
Supported by National Natural Science Foundation of China(Grant No.11971015).
This paper studies the non-homogeneous generalized Riemann-Hilbert(RH)problems involving two unknown functions.Using the uniformization theorem,such problems are transformed into the case of homogeneous type.By the th...

When a laser beam writes on a metallic film,it usually coarsens and deuniformizes grains because of Ostwald ripening,similar to the case of annealing.Here we show an anomalous refinement effect of metal grains:A metal...

On Quaternionic 3 CR-Structure and Pseudo-Riemannian Metric
《Applied Mathematics》2018年第2期114-129,共16页Yoshinobu Kamishima 
A CR-structure on a 2n +1-manifold gives a conformal class of Lorentz metrics on the Fefferman S1-bundle. This analogy is carried out to the quarternionic conformal 3-CR structure (a generalization of quaternionic CR-...

Survey on Discrete Surface Ricci Flow被引量:1
《Journal of Computer Science & Technology》2015年第3期598-613,共16页章敏 曾薇 郭任 罗锋 顾险峰 
Ricci flow deforms the Riemannian metric proportionally to the curvature, such that the curvature evolves according to a nonlinear heat diffusion process, and becomes constant eventually. Ricci flow is a powerful comp...

Liouville Energy on a Topological Two Sphere
《Communications in Mathematics and Statistics》2013年第4期369-385,共17页XiuXiong Chen Meijun Zhu 
We thank Yuxiang Li for pointing out the proof of Lemma 3.5 in an early version is incomplete.We also thank the referee for the careful reviewing and comments.
In this paper we shall give an analytic proof of the fact that the Liouville energy on a topological two sphere is bounded from below.Our proof does not rely on the uniformization theorem and the Onofri inequality,thu...
