  • For a finite group $G$, we construct a simplified model for the $G$-symmetric monoidal $G$-$\infty$-category of rational $G$-spectra. Using this model, we classify $\mathcal{I}$-normed algebras in rational $G$-spectra for a given indexing system $\mathcal{I}$. We show that such an algebra is equivalently described as a collection $\{\mathcal{X}(G/H)\}_{(H\leq G)}$ of commutative algebras in nonequivariant rational spectra, indexed by conjugacy classes of subgroups of $G$, together with compatible morphisms of commutative algebras $\mathcal{X}(G/K)\xrightarrow{}\mathcal{X}(G/H)$ whenever $K\leq H$ and the induced map $G/K\xrightarrow{}G/H$ is in $\mathcal{I}$. This generalizes a result by Wimmer arXiv:1905.12420.
