Higher Galois for Segal Topos and Natural Phenomena
Abstract
Toen and Vezzosi showed that is a Segal groupoid, for a Segal topos, the Segal category of locally constant stacks on a CW complex . Taking the realization of such a groupoid defines a pro-object that is defined to be the homotopy shape of the topos . What we do instead is fix a Segal topos , we let vary, and use the fact that is a fundamental -groupoid. We then prove that is a localization of the Segal category of local systems on , in the spirit of Hoyois' work in his "Higher Galois Theory" paper, where it is proved, morally, that local systems on are equivalent to itself. We provide one application of this formalism, regarding the Segal topos of derived stacks, for a commutative ring, as corresponding to manifestations of natural laws, themselves modeled by simplicial algebras, objects of .

16 pages. Comments added, graphs simplified, proofs of Thm 3.1 and 3.2 rewritten, with lemmas. Emphasis is put on a dual adjunction in those proofs. Functoriality of this adjunction in $T$ is incorrect. It's removed in favor of a universal map, without altering the rest of the paper. Statements about the localization of $\mathcal{X}$ generalized to the setting of perceptions throughout
