我们根据所有 1<p<∞ 的 w 的 Apcharacteristic 证明了内在平方函数(最近由 M. Wilson 引入)的尖锐 Lp(w) 范数不等式。这意味着经典 Lusin 面积积分 S(f)、Littlewood-Paley g 函数及其连续类似物 Sψ 和 gψ 也存在同样的尖锐不等式。此外,作为推论,对于所有 1<p⩽3/2 和 3⩽p<∞ 的任何卷积 Calderón-Zygmund 算子,以及 3⩽p<∞ 的最大截断,我们都获得了尖锐的加权不等式。
We prove sharp Lp(w) norm inequalities for the intrinsic square function (introduced recently by M. Wilson) in terms of the Apcharacteristic of w for all 1<p<∞. This implies the same sharp inequalities for the classical Lusin area integral S(f), the Littlewood–Paley g-function, and their continuous analogs Sψand gψ. Also, as a corollary, we obtain sharp weighted inequalities for any convolution Calderón–Zygmund operator for all 1<p⩽3/2 and 3⩽p<∞, and for its maximal truncations for 3⩽p<∞.
