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…

Common upper frequent hypercyclicity
Monia Mestiri
Considering a family of upper frequently hypercyclic operators we care about the existence of vectors which are upper frequently hypercyclic for any operator of this family. We est…
