摘要: In this talk, we introduce area operators $\mathbb{A}_{\mu,l}$ in the Dirichlet series setting for $l>0$ and positive Borel measures $\mu$ on the right half-plane $\C_0$. It is proved that if $\mu$ is a Carleson measure on $\C_0$, then for $0<p<\infty$, the area operator $\mathbb{A}_{\mu,l}$ is bounded from the Hardy space $\mathscr{H}^p_0$ of Dirichlet series vanishing at $+\infty$ to some $L^p$-space. Moreover, if $\mu$ is a Carleson measure for the conformally invariant Hardy space $H^p_{\i}(\C_0)$, then $\mathbb{A}_{\mu,l}$ is bounded on the Hardy space $\mathscr{H}^p$ of Dirichlet series. We also give an application to Volterra operators.
