The celebrated Fefferman theorem on the general form of a linear functional on the Hardy space \(H^1\) is generalized to the case of an arbitrary compact abelian group with totally ordered dual. This leads to several corollaries that, in turn, can be applied to multiple lacunary Fourier series and to atomic characterization of the Hardy space on the two-dimensional torus.
