Universal families and hypercyclic operators

KG Grosse-Erdmann - Bulletin of the American Mathematical Society, 1999 - ams.org
Analysis is the study of limiting processes. Not every limiting process, of course, converges,
but examples have been found where processes diverge in a maximal way. Such an …

Weak Supercyclicity—An Expository Survey

CS Kubrusly - Results in Mathematics, 2024 - Springer
This is an exposition on supercyclicity and weak supercyclicity, especially designed to

Operators commuting with the Volterra operator are not weakly supercyclic

S Shkarin - Integral Equations and Operator Theory, 2010 - Springer
We prove that any bounded linear operator on L p [0, 1] for 1≤ p<∞, commuting with the
Volterra operator V, is not weakly supercyclic, which answers affirmatively a question raised …

Volterra-Choquet nonlinear operators

SG Gal - 2021 - projecteuclid.org
In this paper we study to what extent properties of the classical linear Volterra operators can
be transferred to the nonlinear Volterra-Choquet operators, obtained by replacing the …

F Leon-Saavedra, A Piqueras-Lerena - Banach Center Publications, 2007 - Citeseer
A bounded linear operator T defined on a Banach Space X is said to be supercyclic if there
exists a vector x∈ X such that the projective orbit {λTnx: λ∈ C, n∈ N} is dense in X. The aim …
