众所周知,Littlewood-Paley算子在调和分析和偏微分方程中起着非常重要的作用。1975年,Calderón和Torchinsky在[1]中考虑了抛物型Littlewood-Paley算子的Lp(1< p<∞)有界性.为了说明Calderón和Torchinsky的结果,我们给出了混合齐性空间的定义.固定aj≥ 1(j= 1,2,...,n),对于ρ> 0且x=(x1,...,xn)∈ Rn,令
It is well-known that the Littlewood–Paley operators play a very important role in harmonic analysis and PDE. In 1975, Calderón and Torchinsky in [1] considered the Lp (1< p<∞) boundedness for the parabolic Littlewood–Paley operators. To state Calderón and Torchinsky’s result, we give the definition of mixed homogeneity space. Fix aj≥ 1 (j= 1, 2,..., n), for ρ> 0 and x=(x1,..., xn)∈ Rn, let
