Common hypercyclic vectors for families of backward shift operators [PDF]

open access: yesJournal of Operator Theory, 2017
We provide necessary and sufficient conditions on the existence of common hypercyclic vectors for multiples of the backward shift operator along sparse powers. Our main result strongly generalizes corresponding results which concern the full orbit of the backward shift.

Invariant manifolds of hypercyclic vectors for the real scalar case [PDF]

open access: yesProceedings of the American Mathematical Society, 1999
We show that every hypercyclic operator on a real locally convex vector space admits a dense invariant linear manifold of hypercyclic vectors.

The Specification Property for $C_0$-Semigroups

open access: yes, 2018
We study one of the strongest versions of chaos for continuous dynamical systems, namely the specification property. We extend the definition of specification property for operators on a Banach space to strongly continuous one-parameter semigroups of ...

Luh hypercyclic vector for composition operator

open access: yes
In this paper, we deal with the construction of holomorphic functions on a simply connected domain satisfying that all its derivatives and antiderivatives under a composition operator have a dense orbit. Such functions will be called Luh hypercyclic vectors for the respective composition operator.

An operator on a separable Hilbert space with many hypercyclic vectors [PDF]

open access: yesStudia Mathematica, 1987
Let T be a linear continuous operator acting in a Hilbert space H. A point \(x_ 0\in H\) is said to be cyclic if \(H=span(x_ 0,Tx_ 0,T\) \(2x_ 0,...)\) and hypercyclic if the orbit \((x_ 0,Tx_ 0,T\) \(2x_ 0,...)\) is dense in H. There is given a construction of a separable Hilbert space H (over complexes) and an operator T with a cyclic vector \(x_ 0\)

Hypercyclic and supercyclic linear operators on non-Archimedean vector spaces

open access: yes, 2017
A main objective of the present paper is to develop the theory of hypercyclicity and supercyclicity of linear operators on topological vector space over non-Archimedean valued fields. We show that there does not exist any hypercyclic operator on finite dimensional spaces.

On the complexity of upper frequently hypercyclic vectors

open access: yes
Given a continuous linear operator $T:X\to X$, where $X$ is a topological vector space, let $\mathrm{UFHC}(T)$ be the set of upper frequently hypercyclic vectors, that is, the set of vectors $x \in X$ such that $\{n \in ω: T^nx \in U\}$ has positive upper asymptotic density for all nonempty open sets $U\subseteq X$.
