P7⇀-Factorization of Symmetric Complete Bipartite Multi-Digraphs
摘要:
如果对称完全二部多重有向图
λK
m,n*的有向弧集可以分拆为
λKm,n*的
Pk⇀-因子,则称
λKm,n*存在
Pk⇀-因子分解。对称完全二部多重有向图
λKm,n*存在
P7⇀-因子分解的充分必要条件是:1) 3m≤4n,2) 3n≤4m,3) m+n≡0(mod7),4) 7λmn/[3(m,n)]是整数。
Abstract:
A Pk⇀-factorization λKm,n* is a set of arc-disjoint Pk⇀-factors of λKm,n*. A necessary and sufficient condition for P7⇀-factorization of λKm,n* is that: 1) 3m≤4n, 2) 3n≤4m, 3) m+n≡0(mod7) and 4) 7λmn/[3(m,n)].
