关于与径向测度相关的极大函数在Lp中无量纲估计的缺乏性

On the lack of dimension free estimates in Lp for maximal functions associated to radial measures

A. Criado

摘要:

在最近的一篇文章中,J. Aldaz证明了与有限径向测度相关的中心极大算子的弱L1界不能独立于维数。我们表明,至少对于小p接近1,同样的结果适用于这种措施的密度递减的Lp界。我们还给出了一些具体的例子,包括高斯测度,其中获得了相对于一般情况的更好的估计。

英文摘要:

In a recent article J. Aldaz proved that the weak L1 bounds for the centered maximal operator associated to finite radial measures cannot be taken independently with respect to the dimension. We show that at least for small p near to 1 the same result holds for the Lp bounds of such measures with decreasing densities. We also give some concrete examples, that include Gaussian measure, where better estimates with respect to the general case are obtained.
