A special case is that if W does not vanish anywhere on X and if for every a E A the series L:=,lIa n wr 11n diverges, then the module 'W = dw generated by W is localizable under d.

31]), let me return to the space ~(X; F). Consider a linear subspace Y of ~(X, F) and a seminorm p on Y.

For instance, the set of real numbers under the natural order is a Dedekindcomplete lattice but it is not complete in the earlier sense. Another consequence of the binary intersection property is that F is a Dedekindcomplete lattice. In particular F is an M-space in the sense of S. e. its norm satisfies the relation IIsup{x, y}/1 = sup{/Ix/l, Ilyll} for all x, y ;;a. O. Kakutani proved that such a space F is norm-isomorphic to a space ee(K) for some compact K. The fact that F is Dedekind-complete imposes an additional condition on K: the closure of any open set is open.
