Etale homotopy theory of non-archimedean analytic spaces

Algebraic Topology 2017-08-15 v1

Abstract

We review the shape theory of \infty-topoi, and relate it with the usual cohomology of locally constant sheaves. Additionally, a new localization of profinite spaces is defined which allows us to extend the \'etale realization functor of Isaksen. We apply these ideas to define an \'{e}tale homotopy type functor eˊt(X)\mathrm{\acute{e}t}(\mathcal{X}) for Berkovich's non-archimedean analytic spaces X\mathcal{X} over a complete non-archimedean field KK and prove some properties of the construction. We compare the \'etale homotopy types coming from Tate's rigid spaces, Huber's adic spaces, and rigid models when they are all defined.
