整值均差整除函数

Functions with integer-valued divided differences

Andrew O'Desky

摘要:

设$s_0,s_1,s_2,\ldots$是其$m$次均差为整数值的有理数序列。证明了$s_n$是$n$中的多项式函数,如果$s_n \ll θ^n$对满足$θ< e^{1 + \tfrac{1}{2} + \cdots+ \tfrac{1}{m}} -1$的正数$θ$成立.

英文摘要:

Let $s_0,s_1,s_2,\ldots$ be a sequence of rational numbers whose $m$th divided difference is integer-valued. We prove that $s_n$ is a polynomial function in $n$ if $s_n \ll θ^n$ for some positive number $θ$ satisfying $θ< e^{1 + \tfrac{1}{2} + \cdots+ \tfrac{1}{m}} -1$.
