On Semi-$ + $-Open Sets in Topological Spaces
Keywords:
closed sets, open setsAbstract
In this paper, we used the notion of operator A+ for defining a new class of set which will be called semi-+-open set, besides we define the concepts of generalized semi-+-closed sets and regular generalized semi-+-closed sets. Moreover, some of their properties are shown.
