ON NEARLY STRONGLY LINDELÖF SPACES
In this paper, we introduce a generalization of strongly Lindelöf spaces, which we call nearly strongly Lindelöf spaces depending on preopen covers and give some characterizations and properties of these spaces. We study some properties of the subspaces of nearly strongly Lindelöf spaces and investigate the relation between the nearly Lindelöf spaces and their subspaces. Also, we study the effect of some mappings and decompositions of continuity on these topological properties.
