Lacunarity for Compact Groups

Let G be a compact Abelian group with character group X. A subset Δ of X is called a [unk](q) set (1 < q < ∞) if for all trigonometric polynomials f = [unk](k=1)(n) α(k)χ(k) (χ(1),...,χ(n) [unk] Δ) an inequality ∥f∥(q) [unk] [unk]∥f∥(1) obtains, where [unk] is a positive constant depending only on Δ...
