Statement ( a ) clearly will follow from statement ( b ) . Statement ( b ) follows from
statement ( f ) ; indeed , let | f ( s ) 2 \ g ( s ) ] , and puth ( s ) = g ( s ) / S ( 8 ) if f ( 8 )

We therefore see that , as asserted , statement ( 76 ) holds for each se H ' such
that gi ( a ) = 0 for all a key . Since ( H + V , H ) is a closed subspace of H ' ( cf .
Lemma 2 ) it follows that every s e H ' such that gi ( a ) = 0 for all a € e , belongs to
