• Resumen

  • We investigate Cuntz-Pimsner C*-algebras associated with certain correspondences of the unit circle. We analyze these C*-algebras by analogy with irrational rotation algebras and Cuntz algebras. We study the fixed point algebras of certain actions of finite groups, and calculate the entropy of a certain endomorphism. We also study the induced map of the dual action of the gauge action on K-groups
