摘  要:Let (G; P) be an abelian, lattice ordered group and let X be a compactly aligned, \phi-injective product system over P. We show that the C*-envelope of the Nica tensor algebra is the Cuntz-Nica-Pimsner algebra as defined by Sims and Yeend. We give several applications of this result. In particular, we show that the Hao-Ng isomorphism problem for generalized gauge actions of discrete groups on C*-algebras of product systems has an affirmative answer in many cases, generalizing recent results of Bedos, Quigg, Kaliszewski and Robertson and of the speaker.
