Models for rational $(\infty, 1)$-categories

Algebraic Topology 2025-11-12 v2 Category Theory

Abstract

We introduce rational (,1)(\infty, 1)-categories, which are (,1)(\infty, 1)-categories enriched in spaces whose higher homotopy groups are rational vector spaces. We provide two models for rational (,1)(\infty, 1)-categories, rational complete Segal spaces and rational Segal categories, and we show that they are equivalent.
