Error bounds for direct and composite cubature formulae—I

In this paper direct and composite two dimensional integration formulae are compared, and conditions are given under which certain error bounds turn out to be better for either one or the other approach.

Sommario In questo articolo vengono confrontate formule dirette e formule composte di integrazione numerica in due dimensioni, determinando condizioni sotto cui risultano migliori certi limiti di errore per l'uno o per l'altro approccio.
