TL;DR: In this article, the authors show that an approximate AF flow is a cocycle perturbation of an AF flow on a unital AF algebra A such that there is an increasing sequence of finite-dimensional α-invariant C*-subalgebras of A with dense union.

Abstract: When α is a flow on a unital AF algebra A such that there is an increasing sequence (A
n
) of finite-dimensional α-invariant C*-subalgebras of A with dense union, we call α an AF flow. We show that an approximate AF flow is a cocycle perturbation of an AF flow.

Multiplier cocycles of a flow on a C*-algebra
TL;DR: In this article, it was shown that a flow is approximately inner if and only if the restriction of the flow to a full invariant hereditary C ∗ -subalgebra is almost inner.

Quasi-diagonal flows
TL;DR: In this article, the authors introduce two notions for flows on quasi-diagonal C ∗ -algebras, namely, quasi diagonal and pseudo diagonal flows; the former being apparently stronger than the latter.

Uhf flows and cocycles
TL;DR: In this article, universal UHF flows are defined as flows whose cocycle perturbations are almost conjugate to themselves on a UHF algebra Mk∞ for any k and also presented a characterization of such flows.

TL;DR: This study explores cocycle perturbations on Banach algebras, specifically flows and their uniform continuity, with a focus on nest and quasi-triangular algebras, and demonstrates the existence of cocycle perturbations under certain conditions.
