点wise Hardy不等式与均匀肥厚性的等价性

The equivalence between pointwise Hardy inequalities and uniform fatness

Riikka Korte, Juha Lehrbäck, Heli Tuominen

AI总结:

研究点wise Hardy不等式在域中的有效性与补集的均匀容量密度之间的等价关系,提出新方法并探讨其在度量空间中的应用。

摘要:

我们证明了域中点wise Hardy不等式成立与补集的均匀容量密度之间的等价性。此结果即使在欧几里得空间中也是新的,但我们的方法也适用于一般度量空间。我们还给出了在度量空间中均匀容量密度推导经典积分型Hardy不等式的新透明证明。此外,我们探讨了上述概念与某些Hausdorff内容条件之间的关系。

英文摘要:

We prove an equivalence result between the validity of a pointwise Hardy inequality in a domain and uniform capacity density of the complement. This result is new even in Euclidean spaces, but our methods apply in general metric spaces as well. We also present a new transparent proof for the fact that uniform capacity density implies the classical integral version of the Hardy inequality in the setting of metric spaces. In addition, we consider the relations between the above concepts and certain Hausdorff content conditions.
