Hereditarily Normal Wijsman Hyperspaces Are Metrizable
Jiling Cao, Heikki J. K. Junnila
In this paper, we study normality and metrizability of Wijsman hyperspaces. We show that every hereditarily normal Wijsman hyperspace is metrizable. This provides a partially answe…

Regular Bases At Non-isolated Points And Metrization Theorems
Fucai Lin, Shou Lin, Heikki Junnila
In this paper, we define the spaces with a regular base at non-isolated points and discuss some metrization theorems. We firstly show that a space is a metrizable space, if and…
