    On peak phenomena for non-commutative HH^\infty

    Full text link
    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 HH^\infty-algebra H(M,τ)H^\infty(M,\tau) has unique predual,and moreover some restriction in some of the results of Blecher and Labuschagne are removed, making them hold in full generality.Comment: final version (the presentation of some part is revised and one reference added
