Let E be a row-finite directed graph, let G be a locally compact abelian group with dual group Ĝ = Γ, let ω be a labeling map from E* to Γ, and let (C*(E), G, αω) be the C*-dynamical system defined by ω. Some mappings concerning the AF-embedding construction of $C*(E) \times _{\alpha ^\omega } G$ are studied in more detail. Several necessary conditions of AF-embedding and some properties of almost proper labeling map are obtained. Moreover it is proved that if E is constructed by attaching some… CONTINUE READING
