Abelian Groups in omega-categories
arXiv:1106.5434
Abstract
We study abelian group objects in -categories and discuss the well-known Dold-Kan correspondence from the perspective of -categories as a model for strict -categories. The first part of the paper is intended to compile results from the existing literature and to fill some gaps therein. We go on to consider a parameterized Dold-Kan correspondence, i.e. a Dold-Kan correspondence for presheaves of -categories. The main result is to describe the descent or sheaf condition in terms of a glueing condition that is familiar for 1 and 2-stacks.
