摘要
Using an ergodic inverse theorem obtained in our previous paper, we obtain limit formulae for multiple ergodic averages associated with the action of F-p(omega) = circle plus F-p. From this we deduce multiple Khintchine-type recurrence results analogous to those for a"currency sign-systems obtained by Bergelson, Host, and Kra, and also present some new counterexamples in this setting.
