On the periodicity of some Farhi arithmetical functions

Qing-Zhong Ji, Chun-Gang Ji

Let $k \in N$ . Let $f (x) \in Z [x]$ be any polynomial such that $f (x)$ and $f (x + 1) f (x + 2) ... f (x + k)$ are coprime in $Q [x]$ . We call $$g_{k,f}(n):=\frac{|f(n)f(n+…

Values of coefficients of cyclotomic polynomials II

Chun-Gang Ji, Wei-Ping Li, Pieter Moree

Let a(n,k) be the kth coefficient of the nth cyclotomic polynomial. The first two authors showed in part I that if m is a prime power and n and k range over the non-negative intege…
