Geometric higher groupoids and categories

Algebraic Geometry 2018-01-16 v3

Abstract

In an enriched setting, we show that higher groupoids and higher categories form categories of fibrant objects. The nerve of a differential graded algebra is a higher category in the category of algebraic varieties, where covers are defined to be smooth epimorphisms.
