Let H=H n =C n \_R denote the Heisenberg group, and let \_ r denote the normalized Lebesgue measure on the sphere [(z, 0): |z| =r]. Let (X, B, m) be a standard Borel probability space on which H acts measurably and ergodically by measure preserving transformations, and let ?(\_ r ) denote the operat
