Volterra operator acting on Bergman spaces of Dirichlet series

Carlos Gómez-Cabello, Pascal Lefèvre, Hervé Queffélec

Since their introduction in 1997, the Hardy spaces of Dirichlet series have been broadly and deeply studied. The increasing interest sparked by these Banach spaces of Dirichlet ser…

On some questions about composition operators on weighted Hardy spaces

Pascal Lefèvre, Daniel Li, Hervé Queffélec +1

We first consider some questions raised by N. Zorboska in her thesis. In particular she asked for which sequences every symbol with $φ\in H^…

Old and new results on the Furstenberg sets

Aihua Fan, Hervé Queffélec, Martine Quffélec

This paper is a complement to our previous paper [21]. It surveys the works on the Furstenberg set and its random version . We also present so…

On composition operators on the Wiener algebra of Dirichlet series

Daniel Li, Hervé Queffélec, Luis Rodríguez-Piazza

We show that the symbol of a bounded composition operator on the Wiener algebra of Dirichlet series does not need to belong to this algebra. Our example even gives an absolutely su…

Approximation numbers of composition operators on the space of Dirichlet series

Hervé Queffélec, Kristian Seip

By a theorem of Gordon and Hedenmalm, generates a bounded composition operator on the Hilbert space of Dirichlet series with square-summable…

Some new thin sets of integers in Harmonic Analysis

Daniel Li, Hervé Queffélec, Luis Rodriguez-Piazza

We randomly construct various subsets of the integers which have both smallness and largeness properties. They are small since they are very close, in various meanings, to Sido…
