摘要
研究了一类广义Petersen图P(3n, n)的强边染色问题,得到的结果为:6≤χs′(P(3n, n))≤8,这里χs′(P(3n,n))表示P(3n, n)的强边色数.特别地,当n为偶数,并且n≡1或2(mod 3)时,χs′(P(3n, n))=6.
The strong edge-coloring of a class of generalized Petersen graphs P(3 n, n) is studied in this paper. The following results are obtained: 6≤χs′(P(3 n, n))≤8, where χs′(P(3 n, n)) denotes the strong chromatic index of P(3 n, n). In particular, if n is an even number and n≡1 or 2(mod 3), then χs′(P(3 n, n)) = 6.
