| Abstract： |
n this paper, the authors obtain an Lp-version of Green’s Imprimitivity Theorem for the group Z of integers. More precisely, for X = Z/nZ and the action α of Z on X by translation, it is proved that the full Lp-operator crossed product F p(Z, X, α) is isometrically isomorphic to the spatial Lp-operator tensor product of Mnp and the reduced group Lp-operator algebra Fλp(Z). This solves the Lp-imprimitivity problem raised by Phillips for the group of integers. They also prove that F p(Z, X, α) is isometrically isomorphic to C(S1, Mnp) precisely when p = 2, where S1 denotes the unit circle in the complex plane C.Moreover, they determine the K-theory groups of F p(Z, X, α). |
