Popis: Some more results on L-spaces with the notions of semi-open, pre-open and alpha-open sets are presented in this paper. Such generalized open sets are characterized by using the concepts of closure and interior operator. Some properties of these generalized closed sets along with their mutual relationships are discussed. Furthermore, the main results given in the paper by M. Y. Bakier are proved to be incorrect.
