Spectral properties of some operator matricesSpringer Science and Business Media LLC - Tập 80 - Trang 37-46 - 2003
Il Bong Jung, Eungil Ko, Carl Pearcy
We study the classes of Jordan and n-normal operators, especially from the standpoint of spectral properties. We show that these classes have many of the good spectral properties of normal operators by showing this for a class of operators that contains both of the above-mentioned classes. We then obtain various consequences of our spectral results.

Let
$${\mathcal{S}}$$
be a sequence of finite perfect transitive permutation groups with uniformly bounded number of generators. We prove that the infinitely iterated wreath product in product action of the groups in
