Abstract :
We study certain covering properties in topological spaces by using semi-open covers. A part of this article deals with Menger-type covering properties. The notions of s-Menger, almost s-Menger, star s- Menger, almost star s-Menger, strongly star s-Menger spaces are defined and corresponding properties are investigated.
