The Bing plane and separately continuous mappings (in Ukrainian)
We prove that the Bing plane $mathbb{B}$ is a$sigma$-metrizable but not strongly $sigma$-metrizable. Alsowe show that for $c$-connected topological spaces $X$ and $Y$each separately continuous function $fcolon Ximes Yomathbb{B}$ is constant.
