本文建立了Hardy-Littlewood极大算子在W_1,p(Ω)上的连续性,其中Ω_n是任意子域,1 < p < ∞.进一步证明了同一算子在Triebel-Lizorkin空间Fps,q(Ω)上的有界性和连续性,其中1 < p,q < ∞,0 < s < 1.
Abstract We establish the continuity of the Hardy-Littlewood maximal operator on W1,p(Ω), where Ω ⊂ ℝn is an arbitrary subdomain and 1 < p < ∞. Moreover, boundedness and continuity of the same operator is proved on the Triebel-Lizorkin spaces Fps,q (Ω) for 1 < p,q < ∞ and 0 < s < 1.
