子集和、完备性与着色

Subset sums, completeness and colorings

David Conlon, Jacob Fox, Huy Tuan Pham

摘要:

我们开发了新的技术,使我们能够证明各种各样的结果有关的子集和完整的序列的正整数,包括解决方案,一些长期存在的开放问题。其中包括:Burr和Erdés关于Ramsey完全序列的三个问题的解决方案,Erdés后来提供了350美元的合并总额;密度完全序列的新概念的类似结果; Alon和Erdés关于着色小于$n$的正整数所需的最小颜色数的猜想的解决方案,因此$n$不能被写为单色和;确切确定的极值功能介绍了Erdés和格雷厄姆的整数集,避免了一个给定的子集和,并回答了一个问题,重申了几个作者,一个均匀的加强一个开创性的结果Szemerédi和武对长期等差数列的子集和。

英文摘要:

We develop novel techniques which allow us to prove a diverse range of results relating to subset sums and complete sequences of positive integers, including solutions to several longstanding open problems. These include: solutions to the three problems of Burr and Erdős on Ramsey complete sequences, for which Erdős later offered a combined total of \$350; analogous results for the new notion of density complete sequences; the solution to a conjecture of Alon and Erdős on the minimum number of colors needed to color the positive integers less than $n$ so that $n$ cannot be written as a monochromatic sum; the exact determination of an extremal function introduced by Erdős and Graham on sets of integers avoiding a given subset sum; and, answering a question reiterated by several authors, a homogeneous strengthening of a seminal result of Szemerédi and Vu on long arithmetic progressions in subset sums.
