htthlem

Description: Lemma for htth . The collection K , which consists of functions F ( z ) ( w ) = <. w | T ( z ) >. = <. T ( w ) | z >. for each z in the unit ball, is a collection of bounded linear functions by ipblnfi , so by the Uniform Boundedness theorem ubth , there is a uniform bound y on || F ( x ) || for all x in the unit ball. Then | T ( x ) | ^ 2 = <. T ( x ) | T ( x ) >. = F ( x ) ( T ( x ) ) <_ y | T ( x ) | , so | T ( x ) | <_ y and T is bounded.
