Countable tightness and -bases on Free topological groups
Fucai Lin, Alex Ravsky, Jing Zhang
Given a Tychonoff space , let and be respectively the free topological group and the free Abelian topological group over in the sense of Markov. In this paper,…
The mapping on the free paratopological groups
Fucai Lin, Chuan Liu
Let be the free paratopological group over a topological space . For each non-negative integer , denote by the subset of consisting o…
Locally -compact rectifiable spaces
Fucai Lin, Jing Zhang, Kexiu Zhang
A topological space is said to be a {\it rectifiable space} provided that there are a surjective homeomorphism and an element such t…
Some topological properties of Charming spaces
Xiaoting Li, Fucai Lin, Shou Lin
In this paper, we mainly discuss the class of charming spaces, which was introduced by A.V. Arhangel'skii in [Remainders of metrizable spaces and a generalization of Lindelöf -s…

Two Weak Forms of Countability Axioms in Free Topological Groups
Fucai Lin, Chuan Liu, Jiling Cao
Given a Tychonoff space , let and be respectively the free topological group and the free Abelian topological group over in the sense of Markov. For every $n\i…
