Abstract: Let A={1,2,...,tm+tn}. We shall say that A has the (m,n,t)-balanced constant-sum-partition property ((m,n,t)-BCSP-property) if there exists a partition of A into 2t pairwise disjoint subsets A1,A2,..., At,B1,B2,...,Bt such that |Ai|=m and |Bi|=n, and ∑a∈Aia=∑b∈Bjb for 1≤ i ≤ t and 1≤ j ≤ t. In this paper we give sufficient and necessary conditions for a set A {to have the} (m,n,t)-BCSP-property in the case when m and n are both even. We use this result to show some families of distance magic graphs. | |
