A non-commutative extension of Amar and Lederer’s peak set result is given. As its simple applications it is shown that any non-commutative H∞-algebra H∞(M, τ) has unique predual, and moreover some restriction in some of the results of Blecher and Labuschagne are removed, making them hold in full generality.
