# Simplicial Nerve of an $A_\infty$-category

## Giovanni Faonte

We introduce a functor called the simplicial nerve of an $A_\infty$-category defined on the category of $A_\infty$-categories with values in simplicial sets. We show that the nerve of an $A_\infty$-category is an $(\infty,1)$-category in the sense of J. Lurie. This construction generalizes the nerve construction for differential graded categories given by Lurie. We prove that if a differential graded category is pretriangulated in the sense of A.I. Bondal and M. Kapranov then its nerve is a stable $(\infty,1)$-category in the sense of J. Lurie.

Keywords: $A_\infty$-categories, nerve, higher categories, pretriangulated dg-categories
