Parametrized higher category theory II: Universal constructions

Category Theory 2022-01-11 v2 Algebraic Topology

Abstract

We develop parametrized generalizations of a number of fundamental concepts in the theory of \infty-categories, including factorization systems, free fibrations, exponentiable fibrations, relative colimits and relative Kan extensions, filtered and sifted diagrams, and the universal constructions Ind and PΣP^\Sigma.
