Non‐Diskcyclicity of Bounded Composition Operators on the Little Bloch Space and the Besov Space

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In this paper, we show that there are no diskcyclic composition operators on the little Bloch space ℬ0 and the Besov spaces Bp.

Cyclic Composition operators on Segal-Bargmann space

open access: yesConcrete Operators, 2022
We study the cyclic, supercyclic and hypercyclic properties of a composition operator Cϕ on the Segal-Bargmann space ℋ(ℰ), where ϕ(z) = Az + b, A is a bounded linear operator on ℰ, b ∈ ℰ with ||A|| ⩽ 1 and A*b belongs to the range of (I – A*A)½ ...

The Spectrum of Mapping Ideals of Type Variable Exponent Function Space of Complex Variables with Some Applications

open access: yesJournal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
The topological and geometric behaviors of the variable exponent formal power series space, as well as the prequasi‐ideal construction by s‐numbers and this function space of complex variables, are investigated in this article. Upper bounds for s‐numbers of infinite series of the weighted nth power forward and backward shift operator on this function ...

Supercyclic and Hypercyclic Generalized Weighted Backward Shifts over a Non-Archimedean c0(N) Space

open access: yesMathematics, 2021
In the present paper, we propose to study generalized weighted backward shifts BB over non-Archimedean c0(N) spaces; here, B=(bij) is an upper triangular matrix with supi,j|bij|

The Ring‐Opening Polymerization–Polycondensation (ROPPOC) Approach to Cyclic Polymers

open access: yesMacromolecular Rapid Communications, Volume 41, Issue 14, July 2020., 2020
Ring‐opening polymerization combined with simultaneous polycondensation (ROPPOC) is a new group of polymerizations that enables access to various classes of cyclic polymers such as polypeptides, biodegradable polyesters, polyamides, and polysiloxanes. Abstract A new concept called ring‐opening polymerization–polycondensation (ROPPOC) is presented and ...

{\Gamma}-supercyclicity

open access: yesJournal of Functional Analysis, 2015
We characterize the subsets $\Gamma$ of $\C$ for which the notion of $\Gamma$-supercyclicity coincides with the notion of hypercyclicity, where an operator $T$ on a Banach space $X$ is said to be $\Gamma$-supercyclic if there exists $x\in X$ such that $\overline{\text{Orb}}(\Gamma x, T)=X$.

Mega-earthquake supercycle [PDF]

open access: yesScience, 2017
Geophysics![Figure][1] Aftermath of the 2016 magnitude 7.8 Pedernales earthquake in Ecuador PHOTO: ASSOCIATED PRESS The recent magnitude 7.8 Pedernales earthquake in Ecuador killed nearly 700 people and caused widespread destruction. Nocquet et al. also thought it looked rather familiar.

n-supercyclic operators [PDF]

open access: yesStudia Mathematica, 2002
Let \(T: H\to H\) be a continuous linear operator on a separable Hilbert space. The orbit of a subset \(C\) of \(H\) under \(T\) is the union of the sets \(C,T(C),T^2(C),\dots\)\ . For a natural number \(n\), an operator is called \(n\)-supercyclic if there is an \(n\)-dimensional subspace of \(H\) whose orbit under \(T\) is dense in \(H\).

Disjoint hypercyclicity equals disjoint supercyclicity for families of Taylor-type operators

open access: yesOpen Mathematics, 2018
We characterize disjointness of supercyclic operators which map a holomorphic function to a partial sum of the Taylor expansion. In particular, we show that disjoint hypercyclicity equals disjoint supercyclicity for families of Taylor-type operators ...

Denseness of sets of supercyclic vectors [PDF]

open access: yesMathematical Proceedings of the Royal Irish Academy, 2020
The sets of strongly supercyclic, weakly l-sequentially supercyclic, weakly sequentially supercyclic, and weakly supercyclic vectors for an arbitrary normed-space operator are all dense in the normed space, regardless the notion of denseness one is considering, provided they are nonempty.
