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 26739 \mathcal D=\bigl\{x\in D(\delta): \lim_{n\rightarrow\infty}\delta_n(x)=\delta(x)\bigr\} 26739 of pointwise convergence of the generators. In particular we examine the relationship of D and various cores related to spectral subspaces.
