Some Properties of the \(\text{ A}_{\infty }\)-Nerve

  • Mattia Ornaghi

摘要

The aim of this paper is to prove that the \(\text{ A}_{\infty }\) A -nerve of two quasi-equivalent \(\text{ A}_{\infty }\) A -categories (linear over a commutative ring) are weak-equivalent in the Joyal model structure. As a consequence we prove that the \(\text{ A}_{\infty }\) A -nerve of a pretriangulated \(\text{ A}_{\infty }\) A -category is a stable \(\infty \) -category.
