respectively for the spectrum and the Weyl spectrum of T ; moreover, Weyl's ลฝ . theorem holds for f T q F if ''dominant'' is replaced by ''M-hyponormal,'' where F is any finite rank operator commuting with T. These generalize earlier results for hyponormal operators. It is also shown that there exis
