[EN] An example of a weakly ergodic 3-isometry is provided in [3], we give new examples of weakly ergodic 3-isometries and study numerically hypercyclic m-isometries on finite and infinite dimensional Hilbert spaces. In ...
We obtain new characterizations of Li Yorke chaos for linear operators on
Banach and Fréchet spaces. We also offer conditions under which an operator admits a
dense set or linear manifold of irregular vectors. Some of ...
