    • The l2-order of magnitude of vilenkin-fourier coefficients 

      Younis, Mohammed S.
      Let G be a compact, metrizable, zero-dimensional, abelian gruop,  i.e ., a Vilenkin group. It is well known ([2], [6] for example) that if f belongs to the Lipschitz class Lip (∝, p, G), 0 ≤ ∝ ≤  1, 1 and lt; p ≤ 2, then ...
