Common frequent hypercyclicity
Stéphane Charpentier, Romuald Ernst, Monia Mestiri +1
We provide with criteria for a family of sequences of operators to share a frequently universal vector. These criteria are variants of the classical Frequent Hypercyclicity Criteri…
-Frequent hypercyclicity notions and related weighted densities
Romuald Ernst, Céline Esser, Quentin Menet
We study dynamical notions lying between -frequent hypercyclicity and reiterative hypercyclicity by investigating weighted upper densities between the unweighted upper…
Hypercyclic Algebras for convolution operators of unimodular constant term
J. Bes, R. Ernst, A. Prieto
We study the existence of hypercyclic algebras for convolution operators on the space of entire functions whose symbol has unimodular constant term. In particular, we pr…
Frequent universality criterion and densities
Romuald Ernst, A Mouze
We improve a recent result by giving the optimal conclusion possible both to the frequent universality criterion and the frequent hypercyclicity criterion using the notion of A-den…
