6) Johnson graph
Johnson图
1.
The Johnson graph J(n, k) is defined as follows: Let n and k be fixed positive integers with n≥k, andΩa fixed set of size n.
Johnson图J(n，k)的定义如下：设n，k是固定的正整数且满足n≥k，Ω是大小为n的固定的集合，那么J(n，k)的顶点集由Ω的所有k元子集组成，两个顶点相邻当且仅当这两个顶点对应的k元子集的交的大小为k-1。

In this dissertation, from the construction point of view, using the methods of induction and contradiction, we obtain these conclusions: the incidence chromatic number of Johnson graphsχ_i(J(t,m))=m(t-m+1); When n≡0(mod 4), k is an odd number, incidence chromaticnumber of generalized Petersen graphs is 4; When n≡0(mod 4), k = 2,4; incidencechromatic number of generalized Petersen graphs is 5.
本文从图的结构性质出发,利用归纳法和反证法研究了Johnson图以及若干广义Petersen图的关联着色,得到:Johnson图的关联色数χ_i(J(t,m))=m(t-m+1);当n≡0(mod 4),k为奇数时,广义Petersen图P(n,k)的关联色数χ_i(P(n,k))=4;当k=2,4时,广义Petersen图P(n,k)的关联色数χ_i(P(n,k))=5。

1.古算术名。亦称异乘同除。相当于现代的比例法。清刘衡有《四率浅说》﹑时曰淳有《今有术申》，推阐其术。
