When Does m – n Divide f(m) – f(n)? A Look at
Column-Finite Matrices
1997
Say a sequence of integers { f(n)} has the
divisible differences property if m – n
divides f(m) – f(n) for all m, n.
In this paper, we characterize such sequences.
The results suggest some questions about column-finite (infinite) matrices
which we discuss, posing some conjectures.
