    Abstract

    Let α be an approximately inner flow on a C*-algebra A with generator δ and let δn denote the bounded generators of the approximating flows α(n) We analyze the structure of the set script D = {x ∈ D(δ): lim δn(x) = δ(x)} n→∞ of pointwise convergence of the generators. In particular we examine the relationship of script D and various cores related to spectral subspaces.
