Abstract For certain families of topologies, the existence of a common Sierpiński–Zygmund function (of a common Sierpiński–Zygmund function in the strong sense) is established. In this connection, the notion of a Sierpiński–Zygmund space (of a Sierpiński–Zygmund space in the strong sense) is introduced and examined. The behavior of such spaces under some standard topological operations is considered.

强意义上的谢尔宾斯基-齐格蒙德函数的一些评述

摘要 对于某些拓扑族,存在共同的Sierpiński-Zygmund 函数(强意义上的共同Sierpiński-Zygmund 函数)。在这方面,引入并检验了 Sierpiński-Zygmund 空间(强意义上的 Sierpiński-Zygmund 空间)的概念。考虑了这些空间在一些标准拓扑操作下的行为。
