$H^p$ spaces of Dirichlet series interpolation in $H^2$ embedding inequalities multiplicative Hankel forms failure of Nehari's theorem multiplicative Hilbert matrix Gordon-Hedenmalm theorem approximation numbers for composition operators pullback measure for a composition operator composition operators with linear symbols transference principle for composition operators on $H^2$

Résumé : I will give a survey of the operator theory that is currently evolving on Hardy spaces of Dirichlet series. We will consider recent results about multiplicative Hankel operators as introduced and studied by Helson and developments building on the Gordon-Hedenmalm theorem on bounded composition operators on the $H^2$ space of Dirichlet series.
