Bounded holomorphic functions attaining their norms in the bidual

Under certain hypotheses on the Banach space X, we prove that the set of analytic functions in A<inf>u</inf>(X) (the algebra of all holomorphic and uniformly continuous functions in the ball of X) whose Aron-Berner extensions attain their norms is dense in A<inf>u</inf> (X)....
