摘要: 对于正整数m,p,q,k∈N+(N+为正整数集合),给出一类非连通图St(m)∪Kp,q, 论证了当k>1, 且min{p,q}≥2时, 该图是k优美图; 当k>(q-1)d+1(d>1, d∈N+)时, 图St(m)∪Kp ,q是(k,d)算术图.

关键词: 非连通图, 优美图, 算术图

Abstract: This paper presents a kind of unconnected graph St(m)∪Kp,q for natural numbers m,p,q∈N+(N+ represents the set of positive integers). And it is proved that graph St(m)∪Kp,q is a k-graceful graph when k>1 and min{p,q}≥2, while the graph is a (k,d) arithmetic graph when k>(q-1)d+1(d>1 and d∈N+) .

Key words: disconnected graph, graceful graph, arithmetic graph
