$\infty$-categorical monadicity and descent

Abstract

Riehl and Verity have introduced an "\infty-cosmic" framework in which they redevelop the category theory of \infty-categories using 2-categorical arguments. In this paper, we begin with a self-contained review of the parts of their theory needed to discuss adjunctions and monadicity. This is applied in order to extend to the \infty-categorical context the classical criterion for fully faithfulness of the comparison functor induced by an adjunction. We discuss the relation with previous work in the literature---which primarily uses model-categorical techniques---and indicate applications to descent theory.
