... 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 space ...

... implies ( i ) , and then that ( i ) implies ( iii ) . Proof that condition ( ii ) implies ( i ) . Let { x } be an arbitrary se- quence in A and let X = sp { a } , so that , by Lemma II.1.5 , 2 , is sep- arable . By Theorem 5.1 and ...

... implies N ( p ) = q . We note that N ( C ) CK , while pe K implies that N ( p ) = p . Now , if T K → K is continuous , TN : C → K is continuous and by the preceding lemma has a fixed point . This fixed point is in K ; it is therefore ...
