Hypercyclic subspaces in omega [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2006
AbstractWe show that any countable family of operators of the form P(B), where P is a non-constant polynomial and B is the backward shift operator on ω, the countably infinite product of lines, has a common hypercyclic subspace.

Dynamics of tuples of matrices [PDF]

open access: yes, 2008
In this article we answer a question raised by N. Feldman in \cite{Feldman} concerning the dynamics of tuples of operators on $\mathbb{R}^n$. In particular, we prove that for every positive integer $n\geq 2$ there exist $n$ tuples $(A_1, A_2, ..., A_n ...

Chaos and frequent hypercyclicity for weighted shifts [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2019
Bayart and Ruzsa [Difference sets and frequently hypercyclic weighted shifts. Ergod. Th. & Dynam. Sys. 35 (2015), 691–709] have recently shown that every frequently hypercyclic weighted shift on $\ell ^p$ is chaotic.

Chaos for Cosine Operator Functions on Groups

open access: yesAbstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014
Let 1 ≤ p < ∞ and G be a locally compact group. We characterize chaotic cosine operator functions, generated by weighted translations on the Lebesgue space Lp(G), in terms of the weight condition. In particular, chaotic cosine operator functions and chaotic weighted translations can only occur simultaneously.

Existence of common and upper frequently hypercyclic subspaces [PDF]

open access: yes, 2014
We provide criteria for the existence of upper frequently hypercyclic subspaces and for common hypercyclic subspaces, which include the following consequences.

A remark on the frequent hypercyclicity criterion for weighted composition semigroups and an application to the linear von Foerster-Lasota equation

open access: yes, 2014
We generalize a result for the translation $C_0$-semigroup on $L^p(\R_+,\mu)$ about the equivalence of being chaotic and satisfying the Frequent Hypercyclicity criterion due to Mangino and Peris to certain weighted composition $C_0$-semigroups. Such $C_0$

Difference sets and frequently hypercyclic weighted shifts [PDF]

open access: yes, 2013
We solve several problems on frequently hypercyclic operators. Firstly, we characterize frequently hypercyclic weighted shifts on $\ell^p(\mathbb Z)$, $p\geq 1$.

Hypercyclicity Criterion on Basic Elementary Operator

open access: yesJournal of Advances in Mathematics and Computer Science
Hypercyclicity criterion has been an important tool in the test of hypercyclicity of different operators. This tool has been used by different mathematicians to show that generalized derivations, left and right multiplication operators, operator algebra ...

Powers of Convex‐Cyclic Operators

open access: yesAbstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014
A bounded operator T on a Banach space X is convex cyclic if there exists a vector x such that the convex hull generated by the orbit Tnxn≥0 is dense in X. In this note we study some questions concerned with convex‐cyclic operators. We provide an example of a convex‐cyclic operator T such that the power Tn fails to be convex cyclic.

Hypercyclicity of Composition Operators on Orlicz Function Spaces

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020
In this paper, we discuss the hypercyclic properties of composition operators on Orlicz function spaces. We give some different conditions under which a composition operator on Orlicz spaces is hyper-cyclic or not. Similarly, multiplication operators are
