AI总结:

本文研究了在幂相关底数下,等差数列中同时满足多个底数尼文数的性质,通过稀疏重复数构造证明了相关结论。

摘要:

最近,Harrington、Litman和Wong[ Bulletin of the Australian Mathematical Society, 2024; arXiv:2303.06534]证明了对于任何固定的b≥2,每个等差数列中都包含无限多个底数为b的尼文数。我们使用稀疏的重复数构造来处理同一问题的结构化双底版本,证明了当公差与b互质时,每个等差数列中都包含无限多个同时是b-尼文和b^k-尼文的整数(实际上,我们能够获得同时是b^ℓ-尼文的性质,其中ℓ=1,…,k)

英文摘要:

Recently, Harrington, Litman, and Wong [Bulletin of the Australian Mathematical Society, 2024; arXiv:2303.06534] proved that every arithmetic progression contains infinitely many base-$b$ Niven numbers, for any fixed $b\ge 2$. We use a sparse repunit construction to treat a structured two-base version of the same problem, showing that every arithmetic progression with common difference relatively prime to $b$ contains infinitely many integers that are simultaneously $b$-Niven and $b^k$-Niven (indeed, we can obtain simultaneous $b^\ell$-Niven-ness for $\ell=1,\ldots, k$).
