A relative $2$–nerve

Fernando Abellán García, Tobias Dyckerhoff and Walker H Stern

Algebraic & Geometric Topology 20 (2020) 3147–3182
DOI: 10.2140/agt.2020.20.3147
Abstract

We introduce a 2–categorical variant of Lurie’s relative nerve functor. We prove that it defines a right Quillen equivalence which, upon passage to –categorical localizations, corresponds to Lurie’s scaled unstraightening equivalence. In this –bicategorical context, the relative 2–nerve provides a computationally tractable model for the Grothendieck construction which becomes equivalent, via an explicit comparison map, to Lurie’s relative nerve when restricted to 1–categories.
