Summary:
|
In this paper, we discuss certain
networks on paratopological (or
topological) groups and give positive
or negative answers to the questions
in [Lin2013]. We also prove that a
non-locally compact, $k$-gentle
paratopological group is metrizable if
its remainder (in the Hausdorff
compactification) is
a Fréchet-Urysohn space with a
point-countable cs*-network, which
improves some theorems in
[Liu C., Metrizability of paratopological
$($semitopological$)$ groups,
Topology Appl. 159 (2012), 1415--1420],
[Liu C., Lin S., Generalized metric
spaces with algebraic structures,
Topology Appl. 157 (2010), 1966--1974]. (English) |
