THE EXISTENCE AND UNIQUENESS OF TIME-PERIODIC SOLUTIONS TO THE NON-ISOTHERMAL MODEL FOR COMPRESSIBLE NEMATIC LIQUID CRYSTALS IN A PERIODIC DOMAIN
收藏 引用
Acta Mathematica Scientia 2024年 第3期44卷 947-972页
作者: 陈爽 郭闪闪 许秋菊 School of Mathematical Sciences Chongqing Normal UniversityChongqing401331China
In this paper,we are concerned with a three-dimensional non-isothermal model for the compressible nematic liquid crystal flows in a periodic *** some smallness and structural assumptions imposed on the time-periodic f... 详细信息

A Note on the Existence of Positive Solutions for a Fourth-Order Semilinear Elliptic System
收藏 引用
Acta Mathematica Sinica,English Series 2010年 第7期26卷 1263-1276页
作者: Yu Xia GUO Guang Zhong CHEN Department of Mathematics Tsinghua University Beijing 100084 P. R. China
In this note, we prove the existence of positive solutions to a class of biharmonical systems. Our main ingredients are proving a Liouville type result for biharmonical system in R+^N via the method of moving plane c... 详细信息

收藏 引用
Acta Mathematicae Applicatae Sinica 1999年 第2期15卷 153-162页
作者: 张志涛 Institute of Mathematics the Chinese Academy of Sciences Beijing China
In this paper, we use cone theory and topological degree theory to study superlinear systemof integral equations, and obtain existence theorems for non-trivial solutions; moreover, we applythe results to two-point bo... 详细信息
