Abstract

Several definitions of analyticity of functions on locally compact groups are introduced and tested in connection with the proprties of the Fourier coefficients on a compact solenoid. It is proved that absolute convergence of the Fourier series does not follow from analyticity and that a rapidly decreasing sequence of Fourier coefficients of a function, which is analytic on a dense subset, need not exponentially rapidly decrease. On the other hand, on compact groups functions with exponentially rapidly decreasing Fourier coefficients are analytic.
