摘要
设σ(G,n)是具有下述性质的最小正偶数,每一项和至少为σ(G,n)的n项可图序列π都有一个实现包含G作为子图.本文给出σ(K5-e,7)=32,σ(K5-e,8)=36,以及当n≥9时,σ(K5-e,n)=2[5n2-6].
A sequence π is potentially K5- e graphical if it has a realization containing a n)denote the smallest degree sum such that every graphical .sequence π with σ(π)≥π(K5- e,n) is potentially K5-e graphical. In this paper, we prove that σ(K5-e,7)=32,σ(K5-e,8)=36, and for n≥9.σ(K5-e,n)=2[(5n/6)/2].
