Description: Lemma for ubth . Given that there is a closed ball B ( P , R ) in AK , for any x e. B ( 0 , 1 ) , we have P + R x. x e. B ( P , R ) and P e. B ( P , R ) , so both of these have norm ( t ( z ) ) <_ K and so norm ( t ( x ) ) <_ ( norm ( t ( P ) ) + norm ( t ( P + R x. x ) ) ) / R <_ ( K + K ) / R , which is our desired uniform bound.
