本文给出了风车图 K_3~(4m),K_3~(4m+1)的一种强协调标号法,从而证实了[1]中提出的一个猜想,即 t≡0,(mod4)不仅是风车图 K_3~t 为强协调图的必要条件,还是一个充分条件。
In this paper, a strong coordinate labeling method for windmills K_3 ~ (4m) and K_3 ~ (4m + 1) is given, which confirms the conjecture proposed in [1] that t ≡ 0, Figure K_3 ~ t is a necessary or sufficient condition for a strong coordination graph.
