In this paper we establish a discrete Calderón’s identity which converges in both Lq(ℝn+m) (1<q<∞) and Hardy space Hp(ℝn×ℝm) (0<p≤1). Based on this identity, we derive a new atomic decomposition into (p,q)-atoms (1<q<∞) on Hp(ℝn×ℝm) for 0<p≤1. As an application, we prove that an operator T, which is bounded on Lq(ℝn+m) for some 1<q<∞, is bounded from Hp(ℝn×ℝm) to Lp(ℝn+m) if and only if T is bounded uniformly on all (p,q)-product atoms in Lp(ℝn+m). The similar result from Hp(ℝn×ℝm) to Hp(ℝn×ℝm) is also obtained.
