Higher Segal spaces via higher excision

Algebraic Topology 2020-07-17 v2

Abstract

We show that the various higher Segal conditions of Dyckerhoff and Kapranov can all be characterized in purely categorical terms by higher excision conditions (in the spirit of Goodwillie-Weiss manifold calculus) on the simplex category Δ\Delta and the cyclic category Λ\Lambda.
