Classification of localizing subcategories along t-structures

Algebraic Topology 2024-12-13 v1 Category Theory

Abstract

We study the interplay between localizing subcategories in a stable \infty-category C\mathcal{C} with tt-structure (C0,C0)(\mathcal{C}_{\geq 0}, \mathcal{C}_{\leq 0}), the prestable \infty-category C0\mathcal{C}_{\geq 0} and the abelian category C\mathcal{C}^{\heartsuit}. We prove that weak localizing subcategories of C\mathcal{C}^{\heartsuit} are in bijection with the localizing subcategories of C\mathcal{C} where object-containment can be checked on the heart. This generalizes similar known correspondences for noetherian rings and bounded tt-structures. We also prove that this restricts to a bijection between localizing subcategories of C\mathcal{C}^{\heartsuit}, and localizing subcategories of C\mathcal{C} that are kernels of tt-exact functors -- lifting Lurie's correspondence between localizing subcategories in C0\mathcal{C}_{\geq 0} and C\mathcal{C}^{\heartsuit} to the stable category C\mathcal{C}.
