Supercyclicity in Spaces of Operators
Results in Mathematics, 2015The authors prove a sufficient criterion for the operator \(C_{A,B}:T \mapsto ATB\) to be supercyclic in different algebras of operators on Banach spaces. They also study hypercyclicity and supercyclicity in the space of all bounded operators with respect to the weak\(^\ast\)-topology.

Bulletin of the London Mathematical Society, 2003
This survey describes some recent results on linear subspaces in which all elements, except the zero vector, are supercyclic for a given supercyclic operator. Before stating some results precisely, we need to recall that the set of normal eigenvalues of an operator \(T\), denoted by \(\sigma_0(T)\), is the set of isolated points in the spectrum of \(T\)

On Supercyclicity of Tuples of Operators
Bulletin of the Malaysian Mathematical Sciences Society, 2014This article continues work by \textit{N. S. Feldman} in [J. Math. Anal. Appl. 346, No. 1, 82--98 (2008; Zbl 1148.47008)], and presents several results about supercyclic and hypercyclic \(n\)-tuples \(T=(T_1,\dots,T_n)\) of commuting bounded operators on a separable Banach space \(X\).

An extension of the Vu–Sine theorem and compact-supercyclicity [PDF]
Journal of Mathematical Analysis and Applications, 2007 If (Tt)t⩾0 is a bounded C0-semigroup in a Banach space X and there exists a compact subset K⊆X such thatlim inft→∞ρ(Ttx,K)=0(∀x∈X,‖x‖⩽1), then there exists a finite-dimensional subspace L⊆X such thatlimt→∞ρ(Ttx,L)=0(∀x∈X).If T:X→X (X is real or complex ...

The Volterra Operator is not Supercyclic
Integral Equations and Operator Theory, 2004If \((B,\|.\|_B)\) is a Banach space with norm \(\|.\|_B\), then according to statements of the introduction of this paper, a bounded linear operator \(T\) on \(B\) is said to be supercyclic if there is a vector \(f\) in \(B\) such that \[ \{\lambda_n T^n(f),\,\lambda_n\in \mathbb{C},\;n= 0,1,2,3,\dots\} \] constitutes a dense subspace of \(B\).

Oil Information Technology Journal, 2021
Despite an industry in crisis, a lot is happening in upstream software. Oil IT Journal editor Neil McNaughton reports on the huge data migration effort required to power-on OSDU, on OSDU pushback from the SPE, on Shell’s own (non OSDU) OpenAI initiative, on the strangeness of ‘hiding’ emissions data, on the great conflation of IT and ‘green’, on the ...

Online Material: Additional site maps, plots and correlation fits. The recent 2011 M w 9.0 Tohoku, Japan, and the 2004 M w 9.15 Sumatra–Andaman superquakes have humbled many in earthquake research. Neither region was thought capable of earthquakes exceeding M w∼8.4.

Supercyclicity criteria for $$C_0$$-semigroups
Advances in Operator Theory, 2020The authors first give some conditions for supercyclicity of a \(C_{0}\)-semigroup. They give different supercyclicity criteria and prove their equivalence for \(C_{0}\)-semigroups. Examples of semigroups satisfying the supercyclicity criteria are given.
