A Partition of the Set of Integers
摘要
Abstract
For given integers a,b,whether there exits such a partitionA1,A2,A3 of the set of integers such that any two of n,n+a,n+b are never in the same Ai(i=1,2,3) for every n∈Z-This paper gives a necessary and sufficient condition for this partition to exist.关键词
