Yu-Hin Au, Aaron Robertson, Jeffrey Shallit

摘要:

Pirillo和Varricchio,并独立,Halbeisen和Hungerbuhler考虑了以下问题,开放自1994年:是否存在一个无限的字w在有限子集的Z,使w包含没有两个连续块相同的长度和总和?我们考虑这个问题的一些变化在光范德瓦尔登定理的等差数列。

英文摘要:

Pirillo and Varricchio, and independently, Halbeisen and Hungerbuhler considered the following problem, open since 1994: Does there exist an infinite word w over a finite subset of Z such that w contains no two consecutive blocks of the same length and sum? We consider some variations on this problem in the light of van der Waerden's theorem on arithmetic progressions.
