Let G be a locally compact abelian group, and A (G) the Fourier algebra on G. A Helson set in G is called an SH-set if it is also an S-set for the algebra A (G). In this article we prove that a compact subset K of G is an SH-set if and only if there exists a positive constant b such that: For any disjoint closed subsets Ko and K1 of K, we can find a ...
