Richness of the class of $\mathcal{R}$-maps [3] is investigated. Several consequences for the theory of quasi-$\mathcal{H}$-closed spaces are indicated.
Viene studiata la ricchezza della classe delle $\mathcal{R}$-mappe [3]. Vengono anche indicate numerose conseguenze per la teoria degli spazi quasi-$\mathcal{H}$-chiusi (vedi Lemma 5).
