Zygmund类中函数的可微性

Differentiability of functions in the Zygmund class

Juan Jesus Donaire, Jose G. Llorente, Artur Nicolau

摘要:

本文证明了欧几里得空间中Zygmund类函数有界均差的点集的豪斯多夫维数大于等于1。对小Zygmund类中的函数也证明了一个类似的结果,并构造了一个例子来说明这些结果是尖锐的。

英文摘要:

We prove that the Hausdorff dimension of the set of points where a function in the Zygmund class in the euclidean space has bounded divided differences, is bigger or equal to 1. A similar result for functions in the Small Zygmund class is also proved and an example is constructed to show that these results are sharp.
