Mian results : If X is a S-cmpactness space, and X has finite semi-open set interrec- tion property then(1)If X is a S_2-space, then X is a S_3 *-space; (2)If X is a S_2-space, then X is a S_4 *- space; (3) If X is a S_3 * -space, then X is a S_4 * -space.
主要结论:设X是-S紧空间,且具有有限半开集可交性,则(1)若是S_2-空间,则X是S_3*-空间;(2)若是S_2-空间,则X是S_4*-空间;(3)若是S_3*-空间,则X是S_4*-空间。
