Add to ORKGWe show that a multiplier cocycle of a flow on a non-unital C∗-algebra can be approximated by a norm-continuous cocycle in the strict topology. As an application among others we show that a flow is approximately inner if and only if the restriction of the flow to a full invariant hereditary C∗-subalgebra is approximately inner.
