摘要
研究了哑铃图Cn+Cm+{unv1}的奇优美性和奇强协调性,得到了哑铃图Cn+Cm+{unv1}在n=4k,m=4t以及n=4k+2,m=4t+2时是奇优美图,在n=4k,m=4t时是奇强协调图等结论。
Odd Gracefulness and Odd Strongly Harmoniousness of dumbbell-shape graphs Cn＋Cm＋{unv1} have been studied. We have obtained that dumbbell-shape graphs Cn＋Cm＋{unv1} are Odd Graceful graph when n = 4k, m = 4t and n = 4k ＋ 2, m = 4t ＋ 2 , and that dumbbell-shape graphs Cn＋Cm＋{unv1} are Odd Strongly Harmonious graph when n = 4k,m = 4t.
