On spaceability of shifts-like operators on
Emma D'Aniello, Martina Maiuriello
We prove the spaceability of the set of hypercyclic vectors for {\em shifts-like operators}. Shift-like operators appear naturally as composition operators on , when the un…

On the spectrum of weighted shifts
Emma D'Aniello, Martina Maiuriello
It is well-known that, in Linear Dynamics, the most studied class of linear operators is certainly that of weighted shifts, on the separable Banach spaces and , $1 \l…

Expansivity and strong structural stability for composition operators on spaces
Martina Maiuriello
In this note we investigate the two notions of expansivity and strong structural stability for composition operators on spaces, . Necessary and sufficient…
