Khintchin conjecture and related topics
Aihua Fan, Shilei Fan, Hervé Queffélec +1
Motivated by Khintchin's 1923 conjecture, refuted by Marstrand in 1970, we study the Khintchin class of functions associated to a given increasing sequence of integers. When the Kh…
Integration type operators and point evaluation on weighted Bergman spaces of Dirichlet series
Carlos Gómez-Cabello, Pascal Lefèvre, Hervé Queffélec
The theory of Banach spaces of Dirichlet series has drawn an increasing attention in the recent 25 years. One of the main interest of this new theory is that of defining analogues…
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…
Characterization of weighted Hardy spaces on which all composition operators are bounded
Pascal Lefèvre, Daniel Li, Hervé Queffélec +1
We give a complete characterization of the sequences of positive numbers for which all composition operators on are bounded, where is the space of an…
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…
On Bernstein's inequality for polynomials
Hervé Queffélec, Rachid Zarouf
Bernstein's classical inequality asserts that given a trigonometric polynomial of degree , the sup-norm of the derivative of does not exceed times the sup-norm…
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…
