Abstract
In this paper notions ofm-Lindelöf, meta-m-Lindelöf, para-m-Lindelöf andm-closure preserving property are defined, wherem is any infinite cardinal. The main results are the following:
-
(a)
A topological space ism-Lindelöf if and only if it is meta-m-Lindelöf and it ism-Lindelöf in the sense of complete accumulation point.
-
(b)
A regular topological space is paracompact if and only if it is para-m-Lindelöf and it hasm-closure preserving property for somem.
