Statement ( iv ) clearly implies the continuity of T at 0 ; so ( iv ) implies ( ii ) . This (
i ) , ( ii ) , and ( iv ) are equivalent . If M = sup ( Tx is finite , then for an arbitrary x +
0 , 12 51 Ta ] = [ 01 | 7 ) > M [ 2 ] . This shows that ( iii ) implies ( iv ) . It is obvious ...

That ( 1 ) implies ( 2 ) can be proved in a manner similar to that used in Theorem
14 to show that condition ( 3 ) of that theorem implies ( 4 ) . From Corollary 19 it
follows that S may be embedded as a dense subset of a compact Hausdorff

To each point pe C there corresponds a unique nearest point N ( P ) € K . To see
this , note that Lemma IV . 4 . 2 implies that if { ki } is a sequence in K such that
limina p - k ; [ = inf ker \ p - k | then { k ; } converges , say , to qeK . If { k { } is
