Let 0<p≤1<q<∞and α=n (1/p-1-q). We introduce some new Hardy spaces HKα,q p (Rn) which are the local versions of Hp(Rn) spaces at the origin. Characterizations of these spaces in terms of atomic and molecular decompositions are established, together with their φ-transform characterizatins in M. Frazier and B. Jawerth's sense. We also prove an interpolation theorem for operators on HKα,qp(Rn) and discuss the HKα,qp (Rn)-boundedness of Calderon-Zygmund operators. similar results can also be obtined for the non-homogeneous Hardy spaces HKα,qp (Rn).
