摘要
本文介绍了关于 \({\mathbb {N}}\) 子集 S 的上巴纳赫密度定理的组合证明方法,并提出了对最初由 Li、Tu 和 Ye 建立的定理的有限 IP 集修正。
Combinational Proof for a Theorem Concerning the Upper Banach Density
In this paper, we introduce a combinatorial proof approach for a theorem regarding the upper Banach density of a subset S of \({\mathbb {N}}\) and present a finite IP-set revision of the theorem originally established by Li, Tu, and Ye.
