Linear Structure of Hypercyclic Vectors [PDF]

open access: yes, 1997
A vectorxin a Banach space B is called hypercyclic for a bounded linear operatorT:B→B if the orbit {Tnx:n⩾1} is dense in B. Our main result states that ifTis a compact perturbation of an operator of norm ⩽1 and satisfies an appropiate extra hypothesis ...

Recurrence properties of hypercyclic operators [PDF]

open access: yes, 2014
We generalize the notions of hypercyclic operators, $\mathfrak{U}$-frequently hypercyclic operators and frequently hypercyclic operators by introducing a new notion of hypercyclicity, called $\mathcal{A}$-frequent hypercyclicity.

Complemented hypercyclic subspaces

open access: yes, 2007
A continuous linear operator T : X -> X is said to be hypercyclic if there exists a vector x is an element of X, called hypercyclic for T, such that {T(n)x}(n >= 0) is dense.

Extensions and derivatives of subsymmetric functions

open access: yesFrontiers in Applied Mathematics and Statistics
In the paper, subsymmetric functions on a real or complex Banach space X with a subsymmetric basis are investigated. It is known that subsymmetric polynomials on the Banach space ℓp, 1 ≤ p < ∞ can be simultaneously extended to polynomials on ℓp(𝔄) for

Invariant manifolds of hypercyclic vectors

open access: yes, 1993
We show that any hypercyclic operator on Hilbert space has a dense, invariant linear manifold consisting, except for zero, entirely of hypercyclic vectors.

Remarks on common hypercyclic vectors [PDF]

open access: yes, 2010
We treat the question of existence of common hypercyclic vectors for families of continuous linear operators. It is shown that for any continuous linear operator T on a complex Fréchet space X and a set ? ?

On numerically hypercyclic operators

open access: yes, 2013
According to Kim, Peris and Song, a continuous linear operator $T$ on a complex Banach space $X$ is called {\it numerically hypercyclic} if the numerical orbit $\{f(T^nx):n\in\N\}$ is dense in $\C$ for some $x\in X$ and $f\in X^*$ satisfying $\|x\|=\|f\|=f(x)=1$. They have characterized numerically hypercyclic weighted shifts and provided an example of
