A topological space X is said to be nearly metacompact provided every open cover of X has an open refinement that is point finite on some dense subset of X [HL]. We will discuss some properties of nearly metacompact spaces.
Theorem. A space X is nearly metacompact if and only if every monotone open cover of X has an open refinement point finite on some dense subset of X.
Theorem. Every nearly metacompact lob-space is meta-Lindelöf.
Theorem. Every space can be embedded as a closed subspace of a nearly metacompact space.
