Résumé : The conditioning analysis of sparse approximate block factorizations of Stieltjes matrices developed by Beauwens and Ben Bouzid in [10] is generalized here on the basis of recent improvements of the point factorization analysis. In particular, the scope of the O(h-1) bound previously obtained for a specific class of applications to discrete multidimensional elliptic partial differential equations is substantially extended. © 1991.
