AI总结:

本文研究了可变分数极大算子在可变Lebesgue空间上的权重刻画,扩展了已有结果,并引入了满足新变量Hörmander条件的核类,证明了Coifman-Fefferman不等式和加权不等式。

摘要:

我们刻画了与可变分数极大算子$M_{β(\cdot),r(\cdot)}$在可变Lebesgue空间上有界性的权重类。这一结果扩展了已知的结果,包括对应于分数算子$M_{β(\cdot),1}$的结果。此外,我们引入了一类满足新变量Hörmander型条件$H_{β(\cdot),r(\cdot)}$的核$K$。对于由核$H_{β(\cdot),r(\cdot)}$给出的分数算子$T_{β(\cdot)}$,我们证明了Coifman-Fefferman不等式和可变Lebesgue空间中的加权不等式。最后,我们提供了该变量Hörmander类中核的例子。

英文摘要:

We characterize the class of weights related to the boundedness of variable fractional maximal operator $M_{β(\cdot),r(\cdot)}$ on variable Lebesgue spaces. This extend previously known results, including those corresponding to the fractional operator $M_{β(\cdot),1}$. In addition, we introduce a class of kernels $K$ satisfying a new variable Hörmander-type condition $H_{β(\cdot),r(\cdot)}$. For the fractional operator $T_{β(\cdot)}$ given by a kernel in $H_{β(\cdot),r(\cdot)}$, we prove a Coifman-Fefferman inequality and weighted inequalities in variable Lebesgue space. Finally, we provide examples of kernels in this variable Hörmander class.
