WebThe Krull–Gabriel dimension explains this behavior because it measures how far an abelian category is away from being a length category. For instance, a triangulated category $\mathsf{C}$ is locally finite (see [Reference Krause 26] or Section 4) if and only if the Krull–Gabriel dimension of $\mathsf{Ab}\,\mathsf{C}$ equals at most $0$.
