Nour, T. M. A note on some applications of semi-open sets. (English) Zbl 0888.54004 Int. J. Math. Math. Sci. 21, No. 1, 205-207 (1998). Summary: The object of the present paper is to study the well-known notions of semi-closure, semi-interior, semi-frontier and semi-exterior of a set using the concept of semi-open sets. A semi-isolated point of a set is also defined and studied.
