自由仿拓扑群单位元的邻域基
Neighborhood base at the identity of free paratopological groups
摘要:
V. G. Pestov在吉洪诺夫空间$X$上的马尔可夫自由拓扑群$F(X)$的恒等式上,利用$X$上的精细一致性,描述了一个邻域基.本文利用空间$X$上的精细拟一致性,得到了空间$X$上的马氏自由同胚群$\FP(X)$的Pestov描述的一个类似,并给出了马氏自由同胚群和Graev自由同胚群的一些性质.
英文摘要:
V. G. Pestov described a neighborhood base at the identity of the Markov free topological group $F(X)$ on a Tychonoff space $X$ in terms of the fine uniformity on $X$. In this paper, an analogue of Pestov's description for the Markov free paratopological group $\FP(X)$ on a space $X$ in terms of the fine quasi-uniformity on $X$ is found and some properties of the Markov and Graev free paratopological groups are presented.
