Genuine vs. na\"ive symmetric monoidal G-categories

Abstract

We prove that through the eyes of equivariant weak equivalences the genuine symmetric monoidal GG-categories of Guillou and May [Algebr. Geom. Topol. 17 (2017), no. 6, 3259-3339; arXiv:1809.03017] are equivalent to just ordinary symmetric monoidal categories with GG-action. Along the way, we give an operadic model of global infinite loop spaces and provide an equivalence between the equivariant category theory of genuine symmetric monoidal GG-categories and the GG-parsummable categories studied by Schwede [J. Topol. 15 (2022), no. 3, 1325-1454; arXiv:1912.08872] and the author [New York J. Math. 29 (2023), 635-686; arXiv:2009.07004].
