CONTINUOUS self-mappingS——Ω-EXPLOSIONS
收藏 引用
Chinese Science Bulletin 1988年 第22期33卷 1852-1856页
作者: 周作领 Department of Computer Science Zhongshan University Guangzhou
1. Let (X, d) be a compact metric space, and denote by C0(X, X) the set of all continuous self-mappings of X with C0-topology. Let f∈C0 (X, X) and ε>0. If x,y∈X, an ε-chain from x to y is a finite sequence o... 详细信息

The Existence of Solutions of a Space-Uniform Boltzmann Equation
收藏 引用
Journal of Applied Mathematics and Physics 2020年 第2期8卷 294-300页
作者: Zhihui Ye Rulv Li Department of Mathematics Yunnan Nationalities University Kunming China
Boltzmann equation is an equation which is related to the three variables of x, v, t. In this paper, we mainly study the space-uniform Boltzmann equation which unknown function F is not related to the position variabl... 详细信息

Measure Centre and Minimal Centre of Attraction
收藏 引用
Chinese Science Bulletin 1993年 第7期38卷 542-545页
作者: 周作领 Lingnan College Zhongshan University Guangzhou 510275 PRC
In this note, we give the definition of the minimal centre of attraction for self-mapping on a compact metrizable space (for the case of flow, see Ref. [1]) and prove that the minimal centre of attraction coincides wi... 详细信息
