Weighted inequalities for a superposition of the Copson operator and the Hardy operator

Amiran Gogatishvili, Zdeněk Mihula, Luboš Pick +2

We study a three-weight inequality for the superposition of the Hardy operator and the Copson operator, namely \begin{equation*} \bigg(\int_a^b \bigg(\int_t^b \bigg(\int_a^s f(τ)^p…
