自相似集、熵与加法组合数学

Self similar sets, entropy and additive combinatorics

Michael Hochman

摘要:

这篇文章是最近的结果自相似集的阐述,断言,如果尺寸是小于平凡的上界,然后有几乎重叠的圆柱之间。我们使用关于覆盖数的初等论证给出了该定理的启发式推导。我们还简要介绍了加法组合学,重点是逆定理,这在证明中发挥了关键作用。我们的基本方法避免了许多原来的证明中的技术细节,但也达不到一个完整的证明。在最后一节中,我们讨论了如何启发式的论点变成一个严格的。

英文摘要:

This article is an exposition of recent results on self-similar sets, asserting that if the dimension is smaller than the trivial upper bound then there are almost overlaps between cylinders. We give a heuristic derivation of the theorem using elementary arguments about covering numbers. We also give a short introduction to additive combinatorics, focusing on inverse theorems, which play a pivotal role in the proof. Our elementary approach avoids many of the technicalities in the original proof but also falls short of a complete proof. In the last section we discuss how the heuristic argument is turned into a rigorous one.
