Abstract

Let Ω be a bounded convex domain in Rn(n≥3) and G(x,y) be the Green function of the Laplace operator −Δ on Ω. Let h r p (Ω)={f∈D′(Ω): ∃F∈hp(Rn),s.t. F|ω=f}, by the atom characterization of Local Hardy spaces in a bounded Lipschitz domain, the bound off→∇2(Gf) for every f∈h r p (Ω) is obtained, where n/(n+1)<p≤1.
