Abstract
Let u be harmonic in the upper half-plane and 0<p< ∞. Then u= Re F for some analytic function F of the Hardy class H p if and only if the nontangential maximal function of u is in L p. A general integral inequality between the non-tangential maximal function of u and that of its conjugate function is established.
