Let $X$ be a compact metric space and let $\Lambda$ be a $\Z^k$ ($k\ge 1$)action on $X.$ We give a solution to a version of Voiculescu's problem ofAF-embedding: The crossed product $C(X)\rtimes_{\Lambda}\Z^k$ can be embeddedinto a unital simple AF-algebra if and only if $X$ admits a strictly positive$\Lambda$-invariant Borel probability measure.  Let $C$ be a unital AH-algebra, let $G$ be a finitely generated abelian groupand let $\Lambda: G\to Aut(C)$ be a monomorphism. We show that$C\rtimes_{\Lambda} G$ can be embedded into a unital simple AF-algebra if andonly if $C$ admits a faithful $\Lambda$-invariant tracial state.
