Strict \infty-groupoids are Grothendieck \infty-groupoids

Algebraic Topology 2020-09-07 v2 Category Theory

Abstract

We show that there exists a canonical functor from the category of strict \infty-groupoids to the category of Grothendieck \infty-groupoids and that this functor is fully faithful. As a main ingredient, we prove that free strict \infty-groupoids on a globular pasting scheme are weakly contractible.
