Using

**hypothesis**( c ) , we may write this last equation as ( 5 ) q ( B - ( B , A ; ) ) = 9 ( A1 ) . Now , by**hypothesis**, the map B ~ ( B , Ay ) of A → A has norm at most M2 ( M + ...Page 2449

By

By

**hypotheses**( d ) and ( e ) , this last equation would follow from ( 4 ) A + 4 ( A , A ) - A , A1 ) = A1 ; thus , to solve ( 1 ) , we have only to ... Since , by**hypothesis**, 6 Mt 31 , we have In + 1 < 2t , and our assertion follows .### What people are saying - Write a review
