Constructing Psuedo- $τ$ -fine Precompact Groups

Dekui Peng, Gao Zhang

Let $τ$ be an uncountable cardinal. The notion of a \emph{ $τ$ -fine} topological group was introduced in 2021. More recently, H. Zhang et al. generalized this concept by defining ps…

Successors of topologies of connected locally compact groups

Dekui Peng, Zhiqiang Xiao

Let $G$ be a group and $σ, τ$ be topological group topologies on $G$ . We say that $σ$ is a successor of $τ$ if $σ$ is strictly finer than $τ$ and there is not a group topology prop…
