Kishimoto's result on the simplicity of such crossed products. We also give a necessary and sufficient condition that our algebras become primitive, and compute the Connes spectra and K-groups of our algebras.Operator Algebras46L55The ideal structures of crossed products of Cuntz algebras by quasi-free actions of abelian groupstext
