摘要
In this paper we establish new L1-type estimates for the classical Riesz potentials of order α ∈ (0,N): ||Iαu|| LN/(N-α)(ℝN) le; C||Ru|| L1(ℝN; ℝN). This sharpens the result of Stein and Weiss on the mapping properties of Riesz potentials on the real Hardy space H1(ℝN) and provides a new family of L1-Sobolev inequalities for the Riesz fractional gradient.
