Abstract
In the following let V(X) be the full superstructure over an appropriate infinite set X containing ℂ and containing also the normed linear spaces we want to consider. Since sometimes we also have to look at Banach spaces which are not a priori in our superstructure we first of all prove the following helpful lemma. For an explicit application see 2.6.
