The specification property for composition operators

Nilson C. Bernardes, Emma D'Aniello, Martina Maiuriello

It is known that the operator specification property does not coincide, in general, with other notions of chaos in linear dynamics. In this paper, we show that, for a natural and w…

On the Dynamics of Weighted Composition Operators II

Nilson C. Bernardes, Antonio Bonilla, João V. A. Pinto

We establish complete characterizations of various notions of expansivity for weighted composition operators on a very general class of locally convex spaces of continuous function…

On the Dynamics of Weighted Composition Operators

Nilson C. Bernardes, Antonio Bonilla, João V. A. Pinto

We study the properties of power-boundedness, Li-Yorke chaos, distributional chaos, absolutely Cesàro boundedness and mean Li-Yorke chaos for weighted composition operators on $L^p…

Li-Yorke Chaotic Weighted Composition Operators

Nilson C. Bernardes, Fernanda M. Vasconcellos

We establish complete characterizations of the notion of Li-Yorke chaos for weighted composition operators on spaces and on spaces. As a consequence, we obtain si…

On the Stability of Generalized Hyperbolic Operators

Nilson C. Bernardes

Our main goal is to prove that every invertible generalized hyperbolic operator on a Banach space has a stability property, known as time-dependent stability, which was introduced…

Generalized Hyperbolicity, Stability and Expansivity for Operators on Locally Convex Spaces

Nilson C. Bernardes, Blas M. Caraballo, Udayan B. Darji +2

We introduce and study the notions of (generalized) hyperbolicity, topological stability and (uniform) topological expansivity for operators on locally convex spaces. We prove that…

On Shadowing and Chain Recurrence in Linear Dynamics

Nilson C. Bernardes, Alfredo Peris

In the present work we study the concepts of shadowing and chain recurrence in the setting of linear dynamics. We prove that shadowing and finite shadowing always coincide for oper…

Uniformly Positive Entropy of Induced Transformations

Nilson C. Bernardes, Udayan B. Darji, Rômulo M. Vermersch

Let be a topological dynamical system consisting of a compact metric space and a continuous surjective map . By using local entropy theory, we prove that $…

A generalized Grobman-Hartman theorem

Nilson C. Bernardes, Ali Messaoudi

We prove that any generalized hyperbolic operator on any Banach space is structurally stable. As a consequence, we obtain a generalization of the classical Grobman-Hartman theorem.

Shadowing and structural stability in linear dynamical systems

Nilson C. Bernardes, Ali Messaoudi

A well-known result in the area of dynamical systems asserts that any invertible hyperbolic operator on any Banach space is structurally stable. This result was originally obtained…

Li-Yorke Chaos for Composition Operators on -Spaces

N. C. Bernardes, U. B. Darji, B. Pires

Li-Yorke chaos is a popular and well-studied notion of chaos. Several simple and useful characterizations of this notion of chaos in the setting of linear dynamics were obtained re…

Expansivity and Shadowing in Linear Dynamics

Nilson C. Bernardes, Patricia R. Cirilo, Udayan B. Darji +2

In the early 1970's Eisenberg and Hedlund investigated relationships between expansivity and spectrum of operators on Banach spaces. In this paper we establish relationships betwee…

On the Dynamics of Induced Maps on the Space of Probability Measures

Nilson C. Bernardes, Rômulo M. Vermersch

For the generic continuous map and for the generic homeomorphism of the Cantor space, we study the dynamics of the induced map on the space of probability measures, with emphasis o…

Graph Theoretic Structure of Maps of the Cantor Space

Nilson C. Bernardes, Udayan B. Darji

In this paper we develop unifying graph theoretic techniques to study the dynamics and the structure of the space of homeomorphisms and the space of self-maps of the Cantor space.…
