我们描述了一类O非线性算子,它们在lizorkin - triiebel空间Fs p,q(Rn)上有界,对于0 < s < 1和1 < p,q < 1。作为推论,我们证明了当0 < s < 1和1 < p,q < 1时,Hardy-Littlewood极大算子在Fs p,q(Rn)上有界;推广了对Sobolev空间H1 p (Rn)有效的Kinnunen[9]的结果。
We describe a class O of nonlinear operators which are bounded on the Lizorkin–Triebel spaces Fs p,q(Rn), for 0 < s < 1 and 1 < p, q < 1. As a corollary, we prove that the Hardy-Littlewood maximal operator is bounded on Fs p,q(Rn), for 0 < s < 1 and 1 < p, q < 1 ; this extends the result of Kinnunen [9], valid for the Sobolev space H1 p (Rn).
