Hypercyclicity criteria and the Mittag-Leffler theorem

(Volume 70 - Année 2001 — Numéro 4 - 5 - 6)
Open Access
Mots-clés : hypercyclic vector


We show that different hypercyclicity criteria are equivalent by using the abstract version of Mittag-Leffler theorem. We also reduce to the context of invertible operators an open problem of Herrero which asks about the hypercyclicity of the direct sum of a hypercyclic operator with itself.
