Abstract: In this paper, we extend the "compact operator" part of Voiculescu's theorem on approximate equivalence of unital *-homomorphisms of an AF algebra when the range is in a countably decomposable, semifinite, properly infinite von Neumann factor. We also extend a result of Hadwin for approximate summands of representations into a finite von Neumann factor.
