Hypercyclic operators with an in¯nite dimensional closed subspace of periodic points
Let \(X\) be an infinite-dimensional real or complex separable Banach space \(X\). If \(T\) is a bounded operator on \(X\), a vector \(x\) of \(X\) is said to be hypercyclic for \(T\) if the orbit of \(x\) under \(T\), that is, the set \(\{T^{n}x: n \geq 0 \}\), is dense in \(X\).

Strongly mixing convolution operators on Fr\'echet spaces of holomorphic functions [PDF]
A theorem of Godefroy and Shapiro states that non-trivial convolution operators on the space of entire functions on $\mathbb{C}^n$ are hypercyclic. Moreover, it was shown by Bonilla and Grosse-Erdmann that they have frequently hypercyclic functions of ...

Hypercyclic subspaces in omega
A continuous linear operator \(T\) acting on a Fréchet space \(X\) is called hypercyclic if there exists a vector \(x\in X\) whose orbit Orb\((T,x)=\{x, T(x), T^2(x), \ldots\}\) is dense in \(X\). Such a vector \(x\) is called a hypercyclic vector for \(T\). A hypercyclic manifold for \(T\) is a dense, invariant subspace of \(X\) consisting entirely --

The main aim of this paper is to investigate generalized asymptotical almost periodicity and generalized asymptotical almost automorphy of solutions to a class of abstract (semilinear) multiterm fractional differential inclusions with Caputo derivatives. We illustrate our abstract results with several examples and possible applications.

S‐Mixing Tuple of Operators on Banach Spaces
We consider the question: what is the appropriate formulation of Godefroy‐Shapiro criterion for tuples of operators? We also introduce a new notion about tuples of operators, S‐mixing, which lies between mixing and weakly mixing. We also obtain a sufficient condition to ensure a tuple of operators to be S‐mixing.

Hypercyclic Behavior of Translation Operators on Spaces of Analytic Functions on Hilbert Spaces
We consider special Hilbert spaces of analytic functions of many infinite variables and examine composition operators on these spaces. In particular, we prove that under some conditions a translation operator is bounded and hypercyclic.

Subspace-diskcyclic sequences of linear operators [PDF]
A sequence ${T_n}_{n=1}^{infty}$ of bounded linear operators on a separable infinite dimensional Hilbert space $mathcal{H}$ is called subspace-diskcyclic with respect to the closed subspace $Msubseteq mathcal{H},$ if there exists a vector $xin mathcal{H}

An Extension of Hypercyclicity for N‐Linear Operators
Grosse‐Erdmann and Kim recently introduced the notion of bihypercyclicity for studying the existence of dense orbits under bilinear operators. We propose an alternative notion of orbit for N‐linear operators that is inspired by difference equations. Under this new notion, every separable infinite dimensional Fréchet space supports supercyclic N‐linear ...

The Strong Disjoint Blow‐Up/Collapse Property
Let X be a topological vector space, and let ℬ(X) be the algebra of continuous linear operators on X . The operators T1, …, TN ∈ ℬ(X) are disjoint hypercyclic if there is x ∈ X such that the orbit {(T1n(x),…,TNn(x)):n∈ℕ} is dense in X × …×X . Bès and Peris have shown that if T1, …, TN satisfy the Disjoint Blow‐up/Collapse property, then they are ...

In this article we study the hypercyclic behavior of non-convolution operators defined on spaces of analytic functions of different holomorphy types over Banach spaces.
