Abstract
Let G denote a compact monothetic group, and let ρ(x)=αkxk+…+α1x+α0, where α0,…,αk are elements of G one of which is a generator of G. Let (pn)n≥1 denote the sequence of rational prime numbers. Suppose f∈Lp(G) for p>1. It is known that if (Formula presented.) then the limit limn→∞ANf(x) exists for almost all x with respect Haar measure. We show that if G is connected then the limit is ∫Gfdλ. In the case where G is the a-adic integers, which is a totally disconnected group, the limit is described in terms of Fourier multipliers which are generalizations of Gauss sums.
