Pour un espace paracompact \(X\), l'auteur introduit la notion de LF-base: Une base \(\mathcal A\) de \(X\) est une LF-base si tout recouvrement ouvert de \(X\) a un raffinement localement fini dont les éléments appartiennent à \(\mathcal A\). Soient \(X\), \(Y\) des espaces paracompacts dont le produit est encore paracompact et qui admettent des LF-bases \(\mathcal A\) et \(\mathcal B\) respectivement. L'auteur donne des conditions pour que la famille des produits \(A\times B\), \(A\in\mathcal A\) et \(B\in\mathcal B\) soit une LF-base de \(X\times Y\).
