摘要

本文引入并研究了一个新的覆盖概念M-星-林德洛夫。这个覆盖的概念产生于选择假说SS*D，fin（D，D）。还将讨论选择假设SS*D，fin（D，D）的更强形式SS*D、1（D，D）。然后，我们考虑这些性质的较弱版本，包括星形算子的迭代。

On Selectively Star-Lindelof Properties

In this paper a new covering notion, called M-star-Lindelof, is introduced and studied. This notion of covering arises from the selection hypothesis SS*_D,fin(D, D). The stronger form SS*_D,1(D, D) of the selection hypothesis SS*_D,fin(D, D) will also be discussed. We then consider weaker versions of these properties involving iterations of the star operator.

期刊介绍： The Society began publishing Progress Reports right from 1907 and then the Journal from 1908 (The 1908 and 1909 issues of the Journal are entitled "The Journal of the Indian Mathematical Club"). From 1910 onwards,it is published as its current title ''the Journal of Indian Mathematical Society. The four issues of the Journal constitute a single volume and it is published in two parts: issues 1 and 2 (January to June) as one part and issues 3 and 4 (July to December) as the second part. The four issues of the Mathematics Student (another periodical of the Society) are published as a single yearly volume. Only the original research papers of high quality are published in the Journal of Indian Mathematical Society.
