周期映射的算术性质

Arithmetic Properties of Periodic Maps

Zhi-Wei Sun

摘要:

设$ψ_1,...,ψ_k$是从$\Bbb Z$到特征为p的域(其中p为零或素数)的周期映射。假设不能被p整除的正整数$n_1,...,n_k$分别是它们的周期。我们证明了$ψ_1+...+ψ_k$是常数,如果$ψ_1(x)+...+ψ_k(x)$对于|S|连续整数x等于常数,其中S={r/n_s:r=0,.,n_s-1; s=1,...,k}。我们也给出了有限等差数列系统的一些新结果。

英文摘要:

Let $ψ_1,...,ψ_k$ be periodic maps from $\Bbb Z$ to a field of characteristic p (where p is zero or a prime). Assume that positive integers $n_1,...,n_k$ not divisible by p are their periods respectively. We show that $ψ_1+...+ψ_k$ is constant if $ψ_1(x)+...+ψ_k(x)$ equals a constant for |S| consecutive integers x where S={r/n_s: r=0,...,n_s-1; s=1,...,k}. We also present some new results on finite systems of arithmetic sequences.
