Let T be a singular integral operator in Journé's class with regularity exponent ε, w ∈ Aq, 1 ≤ q < 1 + ε, and q/(1 + ε) < p ≤ 1. We obtain the Hpw(R×R)-Lpw (R2) boundedness of T by using R. Fefferman's "trivial lemma" and Journé's covering lemma. Also, using the vector-valued version of the "trivial lemma" and Littlewood-Paley theory, we prove the Hpw (R×R)-boundedness of T provided T*1(1) = T*2(1) = 0; that is, the reduced T1 theorem on Hpw(R×R). In order to show these two results, we demonstrate a new atomic decomposition of Hpw(R×R) ∩ L2w(R2), for which the series converges in L2w. Moreover, a fundamental principle that the boundedness of operators on the weighted product Hardy space can be obtained simply by the actions of such operators on all atoms is given.
