On k-invariants for -categories

arXiv:2011.12723 · doi:10.2140/agt.2025.25.721

Abstract

Every -category can be approximated by its tower of homotopy -categories. In this paper, we prove that the successive stages of this tower are classified by k-invariants, analogously to the classical Postnikov tower for spaces. Our proof relies on an abstract analysis of Postnikov-type towers equipped with k-invariants, and also yields a construction of k-invariants for algebras over -operads and enriched -categories.
