Gowers的一个著名结果指出,对于每个є>0,都有一个图G,使得G的每个є-正则划分(在Szemerédi正则性引理的意义下)都有由1/є中高度多项式的指数塔所给出的阶。在这篇笔记中,我们给出了这一结果的一个新证明,它使用了一种明显更简单和更短的构造和正确性证明。
A celebrated result of Gowers states that for every є>0 there is a graph G such that every є-regular partition of G (in the sense of Szemerédi’s regularity lemma) has order given by a tower of exponents of height polynomial in 1/є. In this note we give a new proof of this result that uses a construction and proof of correctness that are significantly simpler and shorter.
