	abstract = {<p>In a measure space $(X,{\mathcal {A}},\mu )$, we consider two measurable functions $f,g:E\rightarrow {\mathbb {R}}$, for some $E\in {\mathcal {A}}$. We prove that the property of having equal p-norms when p varies in some infinite set $P\subseteq [1,+\infty )$ is equivalent to the following condition: $\begin{aligned} \mu (\{x\in E:|f(x)|\&gt;\alpha \})=\mu (\{x\in E:|g(x)|\&gt;\alpha \})\quad \text { for all } \alpha \ge 0. \end{aligned}$</p>},
