Resumen de Coactions on Cuntz-Pimsner Algebras

S. Kaliszewski, J. Quigg, D. Robertson

• We investigate how a correspondence coaction gives rise to a coaction on the associated Cuntz-Pimsner algebra. We apply this to recover a recent result of Hao and Ng concerning Cuntz-Pimsner algebras of crossed products of correspondences by actions of amenable groups.
