Add to ORKGThe aim of this paper is to define and study the concept of semi generalized Lindelöf (sg − Lindelöf) spaces. Relationships between sg−Lindelöfness and other covering properties, such as Lindelöfness, semi−Lindelöfness and rc−Lindelöfness, are investigated. Several characterizations of such spaces are obtained. Also in this paper we study the subspaces of the sg − Lindelöf spaces and the image of the sg−Lindelöf spaces by sg − continuous and sg − irresolute functions
