Approximation properties and entropy estimates for crossed products by actions of amenable discrete quantum groups

We construct explicit approximating nets for crossed products of C*-algebras by actions of discrete quantum groups. This implies that C*-algebraic approximation properties such as nuclearity, exactness or completely bounded approximation are preserved by taking crossed products by the actions of ame...
