respectively for the spectrum and the Weyl spectrum of T ; moreover, Weyl's Ž . 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
In the investigation of a complex vibrating system containing an isolated nonlinearity, the authors expected to see an evolution of the dynamical complexity similar to the Sarkovskii sequence. It is suggested that this is a misconception, based on the literature.
