Universality on higher order Hardy spaces [PDF]

open access: yes, 2005
We prove a Seidel-Walsh-type theorem about universality of a sequence of derivation-composition operators generated by automorphisms of the unit disk in the setting of the higher order Hardy spaces.

Frequently hypercyclic abstract higher-order differential equations [PDF]

open access: yes, 2018
In this note, we analyze frequently hypercyclic solutions of abstract higher-order differential equations in separable infinite-dimensional complex Banach spaces.

Composition principles for generalized almost periodic functions [PDF]

open access: yes, 2018
In this paper, we consider composition principles for generalized almost periodic functions. We prove several new composition principles for the classes of (asymptotically) Stepanov $p$-almost periodic functions and (asymptotically, equi-)Weyl $p$-almost

Existence and nonexistence of hypercyclic semigroups [PDF]

open access: yes, 2007
In these notes we provide a new proof of the existence of a hypercyclic uniformly continuous semigroup of operators on any separable infinitedimensional Banach space that is very different from –and considerably shorter than– the one recently given by ...
