The countable type properties in free paratopological groups
Fucai Lin, Chuan Liu, kexiu Zhang
A space is of countable type (resp. subcountable type) if every compact subspace of is contained in a compact subspace that is of countable character (resp. countab…
The -property on free topological groups
Fucai Lin, Shou Lin, Chuan Liu
A space is called a -space, if is Tychonoff and the necessary and sufficient condition for a real-valued function on to be continuous is that the restriction…

The -spaces property of free Abelian topological groups over non-metrizable Lašnev spaces
Fucai Lin, Chuan Liu
Given a Tychonoff space , let be the free Abelian topological group over in the sense of Markov. For every , let denote the subspace of $A(X)…
