Fibration categories are fibrant relative categories

Lennart Meier

Algebraic & Geometric Topology 16 (2016) 3271–3300
Abstract

A relative category is a category with a chosen class of weak equivalences. Barwick and Kan produced a model structure on the category of all relative categories, which is Quillen equivalent to the Joyal model structure on simplicial sets and the Rezk model structure on simplicial spaces. We will prove that the underlying relative category of a model category or even a fibration category is fibrant in the Barwick–Kan model structure.
